The plug is a new OS-F, I put it in after it quit for the second time at the D4-D5 shootout. D5 DZ wizard JH worked on it Saturday night, It ran like a monster on Sunday, HS needle out 1-3/4. I went out tonight to practice (lord knows I need it) set the same as it was for rounds 5 and 6 in Muncie and it quit on the opening reverse cuban 8 in Masters. I tried setting the HS needle but it seemed to have no effect on midrange. There is slight stumble going from idle to full throttle, I figured the pump was lean, but richening it did not help the midrange.

I miss my 160DZ. My home field is not kind to unexpected dead stick landings.
