E-Ton Carb. Adjustment **HELP**

[Unknownracer]

Anyone have instructions on how to adjust the carb on a 2000 E-Ton TXL90.  The ATV appears to be reving very high in idle and I needed to lower it.  Also, the two adjustment screws on the carb are for..(Idle, high, or low).??  Any help would be great.

I believe that the only external adjustment on that carb would be for the idle. It would be more towards the top of the carb. Screw in to idle up out to idle down. The other screw that you are seeing, if my guess is right is at the bottom of the carb bowl and it is not an adjustment but a drain.

the two  adjustments  are one  for  idle [ thebig  screw on top] the other  one  is the  air mixture screw [the little one] screw it in for richer  out  for leaner.

Thanks,

Would you know what is the factory setting for the adjustment screws?

my sons quad has the same motor on it.if you look at the carb the big screw is the idle it ours is turned 1 3/4 turns and the smaller screw that sits down in the hole it almost flush with the top of the hole.hope this helps.

If you have changed nothing on the bike and it just all of sudden started doing this you have a vacumn leak. Its either at intake boot or crank seals are leaking.

Both of which are not good. Dont force it to run like this, you could score the piston on the exhaust port side if the intake boot is leaking. You will have to do leakdown tests to find this. Sometimes takes a kit & a vacuum pump to find these, in which case you may want to take it to a good shop. Good luck with it.
