I'm assuming the rev limiter is in the Crane box, otherwise it could be disconnected (we gotta add/run one this season). it is sure looking highly likely.
Yes the rev limiter is inside the box but I can dis-connect the 12v source to the rev limiter.
Which I may very well try today.
I’m going to try a few other things first and I’ll post the results.
I need to pull the plug in cylinder 8 since it seems to be the one missing the worst at the moment.
And put a new plug inn and start some more testing with and without vacuum advance.
And with the rev liimter set at different rpm’s and with it dis connected.
