Captainjohn,

Had the same problem with mine. Per advice recieved, I richened the low-end needle about a turn, got it running then adjusted for the proper transition (Thank you, Jody). Give it a try. I aslo soldered the hole in the butterfly for better draw when choking. Also, installed an NKG plug. Hand chokes and starts well, now. Takes about 10 flips after choking.

Bye the way... Your motto says you never met and engine you didn't like. Did you ever own an MDS?
