I recently rebuilt my 40 hp engine with the bigger bores and was wondering if I would be better off with the original vacuum distributor or 009 mechanical. I am currently running the 009 and it is doing ok. Looking for the fuel efficiency being first priority, then performance second.
Thanks for your input.
(I could put on my original vacuum distributor to compare notes, but I don't have it.) Depending on the discussion here, I will probably buy a new vacuum distributor if it is better than the mechanical.
Thanks for your input.

If your vacuum advance is working, it works best for a daily driver.The 009 works best if your driving style is to have it either floored or hitting the brakes and very little in between.
