318 rebuild/overhaul kit

Set timing and idle speed with the vacuum Advance line plugged, curb idle in neutral with wheels chocked (so the pump load is against engine). Your timing change is mechanical advance. Read the distributor/advance section on this forum and on Al-Par. Do yourself a favor and get a factory service manual to familiarize yourself with what you are getting into. The tuning section will serve you very well with your carb rebuild. You mentioned a mechanical choke. Find some numbers off it and down load ya some pics of carb. Does it appear to be a factory manual choke set up or is it an early carb adapted over to the application?
