1993 zr 580 arctic cat

while giving a little throttle rpms will spike to the point where you have to turn off the sled and restart

happens about every 3rd time you give it throttle then turn off restart back to normal then starts all over again

can someone help me by giving me advice.
does anyone have carb adjustment and specs for makuni 34mm carbs
thanks

So are you saying the throttle is sticking? Give us a little more detail about what exactly is happening.

If the belt is on which it must for accurate testing, look for cracked carb boots.
