Al,

I can't remember the rate but it would = be something=20 like 100:1 to the fuel, even less if memory serves me correctly, maybe=20 150:1.

However the mechanical OMP has two = settings one low=20 at low rpm and them full on at about 2,000 rpm.

I doubt if the OMP speed to the crank = speed would=20 be of much use- Richard Sohn knows the in's and out's of this ( excuse = the=20 pun).
