I'd be inspecting the bottom end seals for signs of leakage on any 2-stroke engine that has constantly changing carburetor type issues. ... when it runs does it fire with a nice clear compression pop-pop-pop or does it have a ring-ying-ying engine sound ? I'm still on my idling problem. I can't describe the noise the engine makes. On the other hand, when the idling is about right at a slightly high speed, I just have to accelerate by opening the handle, for the revs to drop and the engine to stall. So I have to set the idle to a high speed and it's not easy to drive in the zone. Quote Link to comment Share on other sites More sharing options...

This is the shortest and will show you the basic concepts: https://www.youtube.com/watch?v=kUmeyVcnZrs Quote Link to comment Share on other sites More sharing options...
