idle high and low, high and low
I have a Znen 50cc gy6 that after it heats up it has an idle issue. It revs high and then low, over and over. I think the idle jet is dirty but wanted to others opinions on the matter. I don't think it's the auto chike because it's after it heats up and the choke is off.

Spray your intake manifold with WD-40 while it's idling. It sounds like you have a vacuum leak somewhere.

yup, if your idle is hunting you should check th o-ring in the intake manifold and the clamp on the carb, if you have an egr system take the line off the intake manifold and cpver it with your finger and try it
