UPDATE FROM THE OWNER: Just for a quick FYI.....The petcock on the gas tank does have a 100 micron brass mesh filter on it just inside the tank. From the video I'd say it needs a shot of air backflushed through the hose. The black sludge in the carb bowl is obviously from the hose, which is the original one and is well over twenty years old. I'm surprised it didn't leak gas through the length of it. As for the pump.....As per Homelite's recommendation, it was always filled with a 50/50 solution of Prestone Anti-freeze when put in storage. I blew this out with HP air months ago before I gave it to Darren. I had originally planned to go though the machine and put it out along with the generator on the curb for sale. I never got around to that and when I came across Mustie's videos I thought what a good idea it would be to let him have them and a few other things for his videos. I finally got my shed cleaned out! Best everyone, George C.

Just picked my first small engine. Brought it home. Had good spark removed the filter. Still didn't start. Removed and cleaned carb. I now have a free lawnmower. I have nobody to thank but you sir. I've been watching for a while now.

Morning everyone...

So you know someone that works in surgery . Blue towels , white basin . Great channel . You know more than one person should . You are a rare breed . Thanks for sharing . Stay safe .

I'd suggest changing that 20+ year old black fuel line, possibly breaking down inside, causing continued particles that jam the float valve.

Anybody else appreciate the super clear "open" and "close" instructions for the fuel valve? Written in words!

I know you don't do merch, but you should make a Musti1 cup for Taryl.

It always surprises me to see someone that still uses a speedhandle. I inherited two from my dad (a 3/8 and a 1/2") that probably date back to the '40s. I don't use them often, but they sure do come in handy.

I always search on Sunday for a Mustie upload. Thanks for the extra pain in the ass to make the videos Mustie. Its always a pleasure and we get to learn something in the process.

The twin nozzle setup is for soap and wash. The larger tip is a soap tip. Soap won’t draw through the DS injector with a small orifice high pressure tip installed, so you use a larger orifice low pressure tip. It’s supposed to make it easier, but in practice they don’t work that well. I’d switch it to a Quick Connect and get the proper sized high pressure tips and then a black soap tip. Also, all the pro pressure washers were screaming NO!!! when you adjusted the unloader valve. To set the unloader, look up the pump flow and pressure rating, then using a nozzle calculator select a 25 degree nozzle with an orifice size that gets you the closest to the rated pressure at the rated flow. Then, get yourself a pressure washer gauge, put it at the GUN end (this compensates for hose insertion losses), fire the machine then adjust the unloader so it runs at the rated pump pressure with the trigger pulled and only jumps 200-300 psi when you close the trigger. This maximizes the flow of the machine.

Good morning Mustie Fam happy Easter everyone

That rubber bushing on the coupling is called a spider that what’s Lovejoy call it anyway . Enjoy your Sunday morning videos keep them coming . Greetings from Dartmouth Nova Scotia Canada

wonderful...great sunday viewing

Thank you for staying sponsor free.

hell yeah i been waiting all year for crusty to come home . good ole crusty you've been missed !

Eric O demo’ed a really cool scope. Two cameras, one down, one side. You would love it, especially looking at valves and the top of fuel tanks.

Very good Mustie1. I need to do a little maintenance on my power washer…. It has been in the basement not outside so expecting it to be usable at least…. This was a great tutorial..👍👍

I love all these different fixalating video's, because you go the distance to save these misfit machine's. Thanks, and God bless.

You go Mustie1 :) These fixing videos are great entertainment, enjoyable to see professional troubleshooting and not getting dirt on your own hands.

Kinda cool design at the tip, the low pressure is for when you use the soap hoes as it needs low pressure to draw the soap up the tube and then when done flip the wand over and you can jet wash the car. Never seen that before, great video btw from the 🇬🇧

Thanks for having us at the shop Mustie1! Another nice save.

The red fuel filters (screen only inside), are set up for larger micron level filtering on gravity feed fuel. Better than no filter at all.

The previous owner sure did all he could to preserve those machines, I remember when you got them👍👍👍

Good morning Mustie, like to wish you and your family a happy Easter. Take care 👍

This was the first time that I actually figured out something before Mustie1 !! I kept yelling at my monitor to "spin the wand tip over" to use the other spray tip... You are the best, Mustie!!!

Sunday ain't Sunday without Mustie1 and Project Farm 😁

Morning favourite time of week mustie1 big shout out to guy he's inspires very week

Not sure that it was still a needle/seat issue when you kept getting debris in the bowl - possibly from the ? year old fuel line crumbling internally from being crimped with vice-grips. As to filters - your issues may come from using the wrong style filters. Gravity fed fuel systems prefer screen style fuel filters, while pump assisted systems like paper filters better. In this case I would have ditched the factory petcock, installed a barbed fitting, an inline fuel shut-off, and a screen style filter into new fuel line. But enough second guessing - Your videos are always entertaining and informational insights into how machinery works.

What a pleasure to watch a talented mechanic work.

Personally I think the way the pressure washer wand tip switch valve is rather ingenious. It beats having to keep track of several tips to change out physically.

Haha at first I thought that sight glass was totally full not empty, love watching further and finding out something you noticed was true

"Neoprene Nipple" I loved their stuff during the 90s.

That's why I really like this channel "Why just start it when we can take it apart "

Nicely done. Should be a great unit.

There exist inline fuel filters specifically for gravity feed systems. They're just fine metal mesh, not as thorough as a paper filter but it's better than nothing. Briggs has them under part numbers 298090 for a 150 micron red version and 394358 for a 75 micron white version. I'd recommend the red one.

Another project, another valuable learning lesson! Might have been a fairly easy fix but more importantly it’s packed with knowledge so thank you! I’ve heard nightmare stories about using the winter mix in the pump so to be safe I just roll my pressure washer into the basement for the winter months. I’m sure that stuff works, but it’s just easier this way for me cause it’s guaranteed not to freeze and is nicer to go through it in my basement shop vs the garage shop. Anyway, thanks for taking us along, another job well done…👍🏼👍🏼 from this guy!

I was yelling at the screen until 35:00 when he realised how it really works! Now I am happy again

Another good Mustie vid , I think verdegris is the word you were looking for for the growth on the brass.I wish fuel was $5 a gallon here in the UK ,i bought 4.9 litres (1.3 us gallons) and it was £8.19 or $10.7

Watching your vdeos is like a breath of fresh air. When a new one is posted it feels like Christmas morning all over again. I'm serious. I appreciate who you are and what you do so much. I am not without talent myself, and I am gearing up my garage with tools and tool boxes, real ones, and I had a high end body shop for 20 years so I wasn't sparse in the tool department to begin with. I respect that you find older boxes that are in good shape and use those. Your humility, knowledge and attitude are unparalleled. I think I am going to have to share you on my Facebook pages with my 1,200 friends. You're the best.

I would change the fue line out to eliminate the chance it’s full of crud from the old fuel/ mystery oil sludge.

They make 2 kinds of filters , the screen type is used with gravity feeds as in the old sediment bowls . The paper ones are made for use with pressure systems . I also think someone before you put the pump backwards because you need easy access to the black pressure adjustment valve .

Great video. If I could make one suggestion, and you probably thought of this already, a fuel filter might be a good idea. 😁👍

Awesome I've wanted to see inside one of these pumps for a long time.

Morning Mustie…..from a sunny and warm Isle of Man…..👍🇮🇲

Has been a year already. Crusty is coming home, woohoo.

I had a nice generator shutdown. I rebuilt starter, replaced starter switch, replaced coil only to discover the new oil change was a few ounces low. Amazing

Better than any classroom. 👍👍👍Happy Easter Mustie

I love watching your stuff. I always learn or in many cases relearn stuff. You also inspired me to make a platform for push mowers and small power units like snow throwers and the like that mounts on the harbor freight mower lift that I have. thank you for the quality, Videos

Good to see Crusty coming back home

Good Morning Mustie! Good To See You This Morning!

Great video look forward to seeing more videos 👍🍺🇨🇦

Thanks for the videos as always.

Where did you the brake cone? I keep watching every Sunday. Your videos have taught me to be patient and to take my time when doing any repair. Thanks.

This one of my favorite channels that get the like before I watch the videos!! Thanks for sharing, makes for a better Sunday!!

Great to see a legend at work

I love to see you work!!

At last, pressure washers and I know more than Mustie! When you unscrewed that large knob on the unloaded valve you reduced the operating pressure, it would help if there was a pressure gauge fitted. Letting it run for too long with the gun closed and water recycling will cause it to overheat. Most of these washers can suck water in if mains supply isn’t available and you can buy suction kits. Run your mains into a plastic 200 litre barrel or similar and let it fill, it will top up as you close the gun. I used to build them on trailers for contractors mostly with larger Diesel engines and with a large water tank plus a hose reel. Silicone oil or grease is good on the O rings. The pistons are probably a ceramic material, the pump looks to be a copy of those we were using back in the 70s. They’re pretty reliable.

You may want to change out that old fuel line. I suspect that's where your debris is coming from.

Because you are the guy that brings things back to life after they have been put away incorrectly. You should do one-five videos on how you would put different pieces of equipment into long term storage. Like tires and wheels, gas/diesel engines, electric motors/generators. How you think it should be done. Like I would bag tires in some form of inert gas like maybe nitrogen? Back in the old days it was wax paper and cosmoline.

Perhaps a holding tank in your loft - 1/2" to fill it, but will give you better water pressure for the length of time it takes to empty the tank. That's what apartment buildings in the city do to give them water pressure - they are far above where residential pressure would do them any good.

Another great video 📹 👏 👍

The Teledyne "Homelite" branded products were and are pretty decent, using Wisconsin Robin (Fuji) smaller or Teledyne Continental larger engines on a lot of the generators, compressors & washers and also the milspec units intended for military use. Can still get parts for most of these engines. I'd rather have an Onan but these are not bad. Looks like this one runs great & was stored fairly decently.

🎉 you are a amazing person and your videos are really good 😊 you teach us good things on your videos 😅thanks … have a great and safe holiday weekend …

Yeah you need to set an engine speed, as you use different types of nozzles you wouldn't be comfortable able to hold them otherwise. Those rotating ones for outdoor floors with a cap over them is an example. If you turn them to high you have to put a lot of weight on them and they will rotate so fast that the water sprays out on the sides :D

Enjoyed seeing how the guts of that pump worked 👌

Enjoyed as always

Over an hour of Sunday morning entertainment. Thanks!

Great video glad you posted keep them coming thanks

Most probably, the low pressure setting is to siphon up the Soap and high pressure to rinse. That's how mine works.

Happy Easter! I always look forward to your videos!

Engine looks like a Fuji Teledyne Subaru Wisconsin Robin WI-280 7.5hp. Wisconsin contracted with Fuji/Teledyne/Subaru to have them make the smaller engines for the US market while they continued manufacturing the larger industrial small engines that they are famous for. The Japanese engines are high quality and earned Wisconsin's business in the US. I had one on a pressure washer and then moved it to a Tote Gote minibike. Tough as nails, built really well, but will have carb float issues....

Great job! It’s alive!

Thank you so much for the content! I'm learning a lot with your videos, i just wish i had a project to apply that knowledge.

I like that new tool, speed brace! Nice up-grade. 😉

Great job as always! I think that marvel really did a great job at preserving both of those units. I really appreciate what you do, and have been a big inspiration to keep making content for my channel as well. 😎🤘🤘

Marvelous, simply marvelous!

Great job!! 👍 Happy Easter to you and your family!!

Nice work Darren. That pump looks to be a Giant pump. Thanks for posting on Easter day and take care!

Low pressure is for when your using a soap or whatever mixture from the side hose. Then high pressure to rinse it off

That's a genius design with the tips

Hi from uk mustie1 and good episode but at end is this crusty coming home? 💓 missed him on the channel he was always in the background hope he served museum well!👌 thanks for your time and be safe see you soon👍👋

HEY! Hell yeah , good morning and thumbs UP !!

I just recently channeled my inner Mustie. With gas prices the way they are, it got me thinking that I have an old Honda Aero 50 scooter sitting back behind my shed. I had tried screwing with it years before and never got it running right. Now that I have a Sonic cleaner and have watched quite a few hours of mustie videos, I took another stab at the carburetor. Put it in the Sonic cleaner for a while and then poked around all the holes and orifices with a bristle from a wire brush. Blew it all out with air, and now it runs amazing! It's really too bad three of the four turn signals are busted out and missing lenses, the brake lights done work and is broke out, it has no license plate and I have no idea if a title or registration even exists for it. Otherwise, I would love to drive it back and forth to work. The local sheriff or state patrol probably wouldn't like it :( Super fun to ride around the property though.

Thank you I have one that I've been putting off because of lack of knowledge now I can proceed with the repair five stars sir

Happy Easter, Mustie 1. You did good work today. Thanks much.

Happy Easter 🐣 Mustie. Live watching your videos!!!! Gonna have to watch this one later on today. Cooking for the family to come over. Have a great day and keep up the great work!!!

Morning and blessed Easter Mustie Funny I spent 7or 8 hours pressure washing yesterday .

Thank you for sharing.👍👀

Thanks for sharing.

I love mustie sundays!!☺

That was cool! Indoor VW was cool too.

Thats really neat how that nozzle works.

Writing this i have seen 1 min. of the video, and i like it already 😉" Let the games begin!"

How many boomers out there in YTube world feeling nostalgic about stuff "Made in Japan"? At the time, our bitching about the poor quality was universal, but boy, were we proven wrong. Today those memories seem more like the good ole days than I could have ever imagined. Happy Easter y'all.

not to bad a find, you'll get it done ok!

Good morning mate.. hope all is good your end..

That ultrasonic cleaner is amazing.

Made for good viewing bro. Safe travels

Hey Mustie ! pistons from the pump do not "ride" on the surface you cleaned. they only "ride" on the seals. and pistons are ceramic. happy to help you with something once haha ! love the videos man !

The plungers slide in and out of the packing. The packing glands are stuck to the plungers. The green and white "corrosion wouldn't have mattered. The important part of the pump head is where the high pressure seal "seals" against the head and it is the spot right about where you honed. Unfortunately I have to head to the shop and repair a bunch of washers this morning instead of finishing watching. I'll check it out later today when I get home. The valves alsojust pull out and are held in place by an oring. That is a Giant pump.If you decide you need parts.
