Well, actually I do not want to use a carb spacer but when I tried to install my new carb feed lines I ran into a clearance issue (see attached pics) with the Performer intake. Btw, the feed lines are original parts from Quick Fuel for my SS-680-VS carb.
Anyway. A spacer is the only (easy) workaround I can think of right now. I guess a 0.5" spacer won't change the setup dramatically. Any recommendations for good ones or parts to avoid?
