Motor seems to be idling fine and running fine at WOT. But at around 2k rpm it sputters like a coil is going out. Is this normal for a coil to act like this? I’m going to switch my tach to each spark plug lead and see if the coil is truly cutting out and which side. If one is bad I’m going to change both. Valves are right. Started doing it after motor sat unused for almost 2 years.

Have u cleaned carb? A little green crust hiding in a jet maybe. Sure a coil is possible but less likely

sounds like a carb lean at the transition from the pilot to the needle. Or some Gunk in the emulsion tube where the needle rides..

Also you do have an o ring on the AF mix screw? without one you will chase yourself in circles

This may help you understand what Maxxis is saying. It’s not exactly the same as a Mikini but pretty dang close and should illustrate it. 2000rpms is right at the transition point between idle and throttle.
