Have you tried backflushig it to see if there are any trapped particles? In controline we'd always backflush the needle valve assembly when we had those kinds of problems. I wouldn't give up on OS, they are top notch motors. I'm running Thunder Tigers.
I have tried all that. I agree, I shouldn't be having these troubles. Never had troubles with an engine in like this that I couldn't solve. Many many people on here are all having the exact same trouble, so it only seems likely that air is being introduced in the valve somewhere. People keep saying it can't happen, but it is happening. I agree, OS used to be a top notch engine. Notice, I said Used to be!
