What are you guys using in the 22mm carbs. I have heard that the needles in the china ones are not good. What part number or size Klein needle fits?

check out the stuff for red baron or on trail bikes site for the rebuild kits

they have jets (main and pilots) as well as rebuild kits too

I have had no problems with mine yet. Just make sure the jetting is right.

It has a bad stumble in the mid range. once you get though it she runs. I have a wide band O2 A/f gauge I put in the exhaust to tune the main. I heard that the good needles fix that.

What motor are you running?

elec start 110, new carb and intake.

You need a 37 pilot and a 95 main that will fix your problem.

Thank you very much. I will give that a try for sure.

Where'd you get a 37 pilot? 35 and 38s are all I can find....3rd column (9N424-24)

The 37 comes with the 22mm carb and if you have a 110 you just need to change the main to a 95 and you'll be good.
