This helped me fix my 2004 ski doo 800ho. Thank you! I had cleaned the main jets, but didn't take out the small pilot jets that have the tiny holes on the sides. These jets were clogged, and the hole that goes through the long way is tiny. The smallest needle I had in the house wouldn't fit through to clean. I soaked in carb cleaner, blew through with air, and could finally push fishing line through when cleaned. Take your time to find the correct flat head screwdriver to remove jets, not something you want to strip out.

You were just the right answer. Pressure washer was running choke open only and I cleaned it up and it runs perfect.

What do you call KNOWLEDGEABLE and SUBSTANTIAL the answer is Thomas Brian Thanks for sharing what you know with us great tutorial 👍 👌 God bless you and all your family around you Thomas Brian From Nick Ayivor from London England UK 🇬🇧

I think you just answered one of my questions. On my engine, I cannot see through that jet you are showing, but the little side holes are clear. I wasn't sure if I should be able to see right through the jet as well (this engine sat for 7 years) I cleaned everything and fired it up and it sounds great, but would only idle with choke out. Looks like I'll take the carb off again and clean this jet so I can see through it. Thanks for the video

Thank you so much! My carb rebuild kit didn't come with that particular part, so now I'll take it apart and look at that more closely.

Very informational quick to the issue,going to go try that on my Coleman mini bike thank you

Nice and to the point, Thanks!

RIGHT ON. I needed this video. thank you

Got the same problem with my woof splitter. Will only run with the choke pulled out once I press it back in the wood splitter shuts off.

Torch tip cleaner works great to get into those tiny holes if anyone's looking for something small enough to get in there thats what I found worked best or small guitar string but torch tip cleaners are designed for this so your best to go grab yourself a set for couple bucks 👍

I cleaned them as well even with a wire through every jet hole. It still only runs with the choke out . Btw it’s just a small trail master go kart carb

It's called an emulsion tube. Those holes pull air through to atomize the fuel mixture. That's pretty much always the problem when having running issues, or will only run on choke. Blame ethanol for that..

Thanks man , mine was different but I was able to find it and clean it .

I dismantled and clean those holes and more. My runs rough only on choke. Might air/mix screw be off too?

Awesome, ! this works EVERY time !+

Yeah, did all that a million times, does not fix the problem. Want some other answer that says its something other than the idle jet being clogged, because it's not. I can fill the idle jet well with solvent and it will siv right through it. Rebuilt this thing with new parts 50 different times, putting it on and off again, with the same problem. Only runs on choke, and stumbles when you twist throttle. It's not the idle jet, pilot jet, or master jet. I replaced that whole jet with one with clean holes., and made sure fluid goes through all 3 jets.

Thanks ! That helped me out!

If this fixes my probme youll get a hug. Im fighting one with this.

Thank you so very much, needed that info!!!🤔

I’m so lost I bought a new carb and it will only run with choke on doesn’t make any sense to me jets are clean not sure what else it could be

Awesome

Excellent

Thank you I just purchased a 96 YZ 250 and it won’t stay running, unless the choke is on

Cool thanks! 🤓👍🏼😎

Thanks for the video

Good shit! Thanks brother!

I have a 92 Polaris trailboss 350 2 stroke it gets stuck wide open when we first got it was good but the throttle was angled down and wasn't in a normal or comfortable position so I angled it where I thought it would be and that's when the problem started I've readjusted the cable I've twisted it back towards where it was to begin with but it's still sticking would you have any ideas

awesome vid clear and informative. Question, mine starts and runs fine, idles fine, revs up smooth and fine, but i can throttle up to 98% no issue and even hold it there still runs fine, but if i twist that 2% to throttle stop, it dies instantly i let go of the throttle keeps idling over and again,? any ideas? throttle seems clean filter clean. cheerrs

Thank you for sharing

IF ONLY it was that simple........................

Bet you are correct sir

hey buddy, those holes at the sides, is that item supposed to have whole all the way through top to bottom? because mine is having clear side holes, but top to bottom is blocked and I cant push whatver is blocking

Put new carb on 89 kawasaki bayuo and wont run with choke off ??

My 2000 YZ250 has a PWK38S carb. I was reading online that this carb has a power jet. What is a power jet? I only see two jets: the main and pilot. Thanks

thank you!!!!!!

would this also cause a carb to leak ?

👍

So the ports have to be blocked by the housing wen being Inserted???

On my 2001 500 HO I choke it in cold weather and have to hold the throttle a little while it warms up to keep it running. Once it warms up it idles and runs fine. The idle is almost on the high side when warmed up. But when cold the idle seems low. Does anyone know what that issue is?

Not it what else could it be

I cleaned that and my bike will still on run with carb on. Second I turn it off it dies

THERE IS NO POINT IN CLEANING CARBURETORS UNLESS YOU THOROUGHLY CLEAN OUT THE FUEL TANK ALSO OTHERWISE CARBURETORS WILL JUST CLOG UP ALL OVER AGAIN.

What about if it runs and idles but dies when revved up and will only rev up with choke

Did anyone have success with this?

Clean this n bike still only runs on choke
