Quote: Are you running a crank trigger? MSD dist. ? timing locked in at say 35 degrees? I don't think anything is wrong with engine if it runs. Just don't give up, things will work out. We have all been there.
I'm running an MSD trigger and MSD distributor. I can unplug the trigger and plug into distributor and nothing changes. Timing is locked at 31 degrees right now.
I was leaning toward rotor out of phase but your heat clue might be the line to follow. Coil (what type) or MSD box could be fine till they warm up. Heat affects wires also, plug and power wires. What size jets in the carbs, could be way to rich after warm up, kinda like a stuck choke. Where the carbs ever run on another car?
