I'm trying to chase down a problem with my '46 235. the engine lugs on acceleration. I've put in points-condinser, wires, plugs, set timing, and cleaned carb. I replaced the plugs and that was the only step that didn't lead to any improvement. In fact the new plugs probably made the truck run worse.
There were Autolite 4194's gapped to 0.020 in the truck so that's what I replaced them with. I gapped them to 0.040, per the manual. The truck has a pronounce backfire now, that is worse than before. I may go back and cut the gap down some and see if that helps.
Is there another plug, or a different gap that y'all recommend? I've seen an Auotlite 3136 mentioned upon searching the forums. In running these in a '46 two ton, but probably will never really load the old girl that much.
Thanks,
Scott
Forgot to mention these are the small 10mm size plugs.
