Questions for the experts. I was fiddling w the 75-40 today and wondered if the timing should be set any different when running a Howell EFI? Also, if anyone out there has a lot of experience w tuning the Howell system I would love to talk w you as I have a few questions on “ tuning” it.
Also the PO put platinum plugs in. Are these best for overall performance or should I run something else?
Thx
