ORIGINAL: flygilmore

Stop screw is removed.... I initially ran the motor exactly per the instructions @ 32:1 word for word. The idle and all was good at that setting. After the initial run in, I slowly started leaning the low end until it would die on trans. and then richened back up a little. I then leaned top end 1/16 (from stock) and lost rpm so richened the high speed from factory 1.75 to 2 and it picked up RPM making me think that the stock HS was a touch lean. I guess that I am just paranoid about running too lean and causing damage.

Not sure what to do here...leave @ stock needle setting???

Thanks.

Pulled plug last night and it was brown in color with some wetness on the threads
Stock settings are only a start. I think you are doing it right. Leave the high speed rich. You're not paranoid, leaving it too lean on the high speed will damage your engine. If not immediately, in time.
