I want to see that too! With a Reed you're getting your full charge to the top end(instead of 1/4 of it blowing back out the carb). I'll bet the plug is dripping charcoal!Now what does the plug look like?
That was my guess.No, it was starved for fuel. plug was a light to med brown. I'm not sure this engine is going to have enough vacuum to open the reeds at higher rpm's.
