lekker man! guess how i got here? slowing turning into the local gennie guy lol

@@craigstewartStif69Myster 😂👍👍

Looks like you could benefit from batteries and an inverter. Good luck.

@@robertpeters9438 i have. Maybe just more batteries

Good old Marvel Mystery Oil.

I've been running 2 stroke oil and rec fuel in my "occasional use- mostly stored" 4 cycle machines like snowthrowers for 30+ years.

There's just the question of how much is 'a little'. Hopefully way less than 50:1 .

@@sniper7.62x51can i have a quick tutorial i know it sounds dumb but how much oil do you use

@@silvestrepalacios9009 I'll run 1/2 tank of 90 octane rec fuel and 1/2 tank of 40:1 2 stroke mix. Never had any issues. In my mind a little extra lubricity is not going to hurt anything. And I've never had a coked up or fouled out spark plug, or any rust formation in the steel fuel tanks.

Why does the efficiency of the engine matter? The 13HP rating is the mechanical output of the engine, the amount of fuel it burns to achieve that is irrelevant. The characteristics of the engine (just because it says 13HP doesn't mean it can deliver that much at 3600RPM) and the efficiency of the power head is what matters in determining how much electricity can be obtained.

@@thisnthat3530 efficiency is important for energy convertion. A single cylinder gasoline engine is not going to take all of the stored energy in the gasoline and convert it to usable work. There are heat and frictional losses that take away from this. Inherently single cylinder engines are not consistent on power delivery either having a power stroke every four strokes. It is also important to know that horsepower ratings are not always accurate for these engines. You are correct, torque/ horsepower curves all related to RPMs can have an impact on total output produced. Powerhead efficiency is rated in terms of power factor. Generator powerheads are rated in X amount of watts at 1.0 power factor. Realistically however, what matters most is Voltage Amps. It's a metric commonly less used on portable generators because the concept is beyond the average homeowner, real power vs apparent power, as in power not doing any actual work for the load. It is the difference of being able to run a large inductive motor like your 5 Ton central air with a soft start or your portable 1/2HP air compressor. My point in all this is that the science is less understood by the average homeowner thus derived standards like 2 horsepower for every 1 KW are far easier to understand than all the math/calculation/factors that goes into chemical energy to mechanical energy conversion.

@@Bassguitarist1985 Power factor isn't related to efficiency of the powerhead when thinking of the engine power. Reactive energy by definition isn't dissipated in the system but stored and released out of phase, therefore it loads and drives the powerhead equally with a net result of zero. The stator winding must be sized for the additional current (which is why cheap generators always specify W@PF=1 so they can skimp on materials), but the engine doesn't care. The losses due to friction in the bearings, the fan, wire and core losses are the ones that count from the engine's perspective. Also, while the single cylinder engine will be uneven with its power delivery it averages the rating over two revolutions so doesn't need to be higher rated because of that. At 13HP an engine is producing 9700W at the crank. With a 95% efficient power head the electrical load would be 9200VA at PF 1 or 11500VA at PF 0.8 (9200/0.8). In both cases the engine only has to produce 9700W at the crank.

@@thisnthat3530 great info! I recently repaired a portable generator with a 13HP Honda engine. It could not handle more than 6kw resistive load. My guess is that it was not outputting it's full horsepower or it was never able to produce 13 horsepower. Thanks for the info once again!

I second your comment and he makes small engines fun to diagnose and repair. I have learned so much from watching this channel and we all thank you!!!

Exactly what I was thinking when he explained how the decompression mechanism worked.

I've been able to diagnose and repair quite a few generators from watching his videos

Explaining it again at again actually helps to gain viewers. Like this is my first video i saw and i hate to watch another millions video to know what creator means saying 'it was in 123 video you know it'

You and me too!

I own the the 7500E just like this one. That is a different kind of metal on the gen housing , I think it is prone to rust

Once I got the crap out of the cylinder I would have soaked the cylinder with Seafoam, cleaned the carb, and then run it on pure gas with Seafoam and put an ounce of Seafoam in the oil for a half-hour. An oil change and you would have been good to go. Engines want to run. This genset looked good, and getting some of the gunk out is all it needed. Ethanol is what kills these engines, and water. I wonder if this genset got submerged at one point. Be mindful that a lot of what people do has no effect, it's the one or two things that do matter. For instance getting the gunk out of the cylinder not the valve adjustment.

I was definitely tempted to use the original part. Glad I did not.

I thought I was the only one that thought then when seeing Jon's seal meme

Agreed.

Very true. Engines like this are automatically at full throttle when turned off. Once up to speed the governor begins to close the throttle plate to maintain the set speed.

I never understand the neglect these machine receive. A lot in my area also rely on a well for water. No power = no water.

@@jcondon1 Can't run a well pump off a candle!

Thanks Brian

It sure is

Thanks

Thanks for putting the time in. Yes, it is very clear there is some discontinuity in the head between the valves. If I was to take a guess, its a gouge from some tool during manufacturer. I could be dead wrong.

I noticed that potential crack too

Sure looks like a crack to me

I have enough heaters to max out most portable generators. Usually do not unless I suspect an issue. Need to buy a real load bank at some point.

Not sure my drill could have spun it fast enough.

That’s what it’s called Breaker bar racket Thanks I had one but lost it so I’m ordering other one online

They seem to find me. I hate to think about how many are trashed for minor things that could be fixed with just a little time and know how.

Been watching a lot of your videos recently. Could not resist the seal reference when putting the carb back together.

Good point. That would have been easier.

Little Johnny was helping grandpaw

Thanks. Sometimes doing the easy thing works. Removing the head is always better if you want it to be 100%.

Now THAT is some creative content!
