Fuel issues can be mistaken for a "weak spark" condition also! The weak spark fails to properly fire the plug, leaving the plug "wet". Which leads to a "fuel" problem as the likely diagnosis. Of course the worst of both worlds is BOTH, then it's really tough making the diagnosis!
The first question is ALWAYS:
Is it fuel or is it spark?
I had this BRAND NEW Dodge truck (dealership) prepping it for the lot to be sold (carb, this was many years ago). Fouled plugs, ran rich, etc. Tore my hair out trying to find the problem. Electronic ignition. Turns out the reluctor air gap in the distributor was SO close it could barely signal the ignition module to fire the plugs. Weak spark, kicked my butt figuring it out!
Agreed, .032 is fine for gap if not running high energy ignition system. The spark should be BLUE, jump a good distance to ground and have a nice crisp "snap" sound to it. Yellow spark? No "snap" sound? Doesn't jump a good gap (1/2" or so)? Not good!
