Hi Andy,

I went back and read 109, and I understand your analysis led you to believe fuel turbulance at the brass intake hole may have been the problem.

Your last post said to order a new brass insert to solve the problem. I'm not quite sure why the new brass insert will fix the problem.

Originally I stated I drilled both the intake and exhaust nipple and the brass insert to get mine working. I suspect it was the drilling of the brass insert hole larger was the fix for yours, but I'm not quite sure. Can you explain what you think the fix is?

I'm glad to hear the engine is working well, congratulations, your hard work paid off!
