Correct, no wideband gauge yet.

Plugs are impossible to read. I check for the blue heating of the plug. Its at 88 jet front with PV and 94 rear. the hard starting is the telltale symptom here I believe.

But that could something to look at. It is kinda slow all the way down the track.
I have run this same specs of a motor before on race gas and more compression and it was ungodly powerful and fast in my Sapporo.

that gear drive has my mind boggled some. I guess I could put a new chain on it and test it out with straight up or retarded settings
