Engine Vacuum thru range
I have a new ZZ4 Fastburn and want to dial it in. Running a vacuum off the carb I have no reading until I give it some throttle and it jumps to 10-15. Is this how it should be or should I go to direct manifold vacuum? What vacuum readings should I have at say 1000, 2000, 3000 RPM's roughly? I've never tuned this way so bare with this weekend hobbiest.
Cheers, (its Friday)
