Take it easy here. gaRCfield only mentioned the tuning of his YS engine because of what the learned on the air bleed carb. The real point is his tuning tip that applies to all 2-stroke engines.

Very good info and pertinent to beginners learning to tune their engines.

After all, if you're not a beginner, you don't need any advice as you should already know how to tune an engine.
I learned to tune an engine while I was a "beginner".

Keep it up, Joe.
