Maybe 0.7mm is with a 4000 rpm rev limit.
Did I not tell or suggest to him to contact D. Richardson on this?? Mmmmm.
.7mm is the minimum. over 1mm is not the best and both my 948 engines unded up at 1.2mm and i was able to stop using duel spark plugs.

How many engines have you built? My 948 engines saw 7.5k RPM often.

Comments like your's are why most that know will not post in threads of this type.
Lurk & drop turds, is that you?
