Having some engine issues with my new 4btt. The engine has just over a gallon through it. The issue at hand is flame outs. I had a bunch of them Saturday. Now, the only time it was flaming out was down the straight WHEN I would let off throttle. Temps are 230-255ish. Needles both about flush. I'm using the blue carb 6.5mm restricker. I'm also using the c5tgc. I did change to a new plug to see if that prevented the flame outs....no luck. Also, the temp was hot and humid yesterday...about 88 (wi). So, not sure if that could've been a issue....Any idea's?
