Yikes.. How many carbs have you bought over the years ?

The carbs they sell you are set up for some generic bike that will run with the jets and setting they have fitted, but they are almost never set up to the manufacturers specs for any particular bike. They nearly always need some adjustments and doing the work, and figuring what they need, is more work generally than just repairing the original.

In your case here the problem sounds like the transition from the idle circuit to the slide needle controlled part of the circuit, or the slide needle circuit itself.

I'd adjust the idle mixture and speed to get the mixture setting in the center of it's mixture range, with the speed setting as slow as possible. It's very important when you are adjusting the mixture that the butterfly or slide is as closed off as much as possible, and after you have got it set at a slow even setting then you can if you want increase the speed slightly, but don't readjust the mixture once it's at it's best lowest slide/butterfly setting.
Then if the trouble is still there I'd adjust the slide needle one notch and test it. Whether you raise or lower the needle will depend on the symptoms. If it's stumbling and sort of gurgling it is probably too rich, and if it's spitting into the airbox it's probably too lean.

 

I have a few technical term(s) for explaining the quantity of the aftermarket parts I've invested in over the years. The carb count totals up higher than the names I was taught years ago in school. there are no words to describe the number of carbs I've bought.. I have been looking for my name on the side of a Bezo Aviation test rocket Im sure I paid my fair share. The damage the Crap gas at the pump does to these carbs is scary most everyone I've gone to rebuild had pitting or is so far damaged there is no coming back. SO habit I guess, a New project that's been sitting for a long time?... I don't even look I just pay an installment note on the rocket....

thank you first and foremost for all of the time you have taken TO REPLY ... 2 filters were a possibility but I replaced the 2 with a new larger one but the issue remains, I cant find any info on jet adjustment Do I need to pull the carb for each adjustment???

Hey freinds, I picked up a beautimus 02 kaw 220 bayou. What I know about this machine .. Not ran in 4 to 5 yrs after providing seller with yrs of trouble free service . It was left under a tree after the seller bought a larger atv.
After sitting for 5 yrs My 1st gift was
1)fresh oil and filter
2)new gas and "filters" 2 inline
I'll explain in a sec.
3) new amazon carb airfilter and boot to carb
4) Start and ran for 30mins
5) add a little atf fluid rans 3 mins
6) another new oil filter and more new oil
I FORGOT NEW battery also....
I pulled it twice ..not doing that agian
The bike ran like a top no worries besides thee reverse cable will not function as its ment to.
After 3 to 4 weeks it started to die.
I found white crude in the carb from water In the fuel somehow.. not sure how..
So new amazon carb as I boughtv2 the 1st time in case one was crap.
I've bought alot of these cheap carbs only 4 or 5 percent has been problematic ..
So back to a clean tank and added 2 inline filters just incase and it starts runs idles like a new bike . But thus time I have a small stumble in the 1st 10 to 15 percent of throttle travel.
We are in Texas about 130 ft Elevation. Reckon the jets need adjustment or replaced or is there other adjustments I can make.
Cheers joe
