Jeeper
I have a 1978 CJ5 With a AMC 304 V--8 I want to do a tune up because it back-firing alot. So I just need to know what spark plugs to use and at what gap ? Anything else you may think of will be appreciated. Very new to the game. Guess I need start doing some things to this Jewel I have had it a few months and I just can't find time to take care of it.
