Well, it isn't a sputter, it's a quit. When it's hot, my coach quits - or tries to - when shifting. I found out yesterday, I can >usually< nurse it back to life with the accelerator pump but not always. This is the syndrome which put me beside the road on the way to Louisville. I redid the fuel feed, but going over the mountains, it quit on the way to Bean Station. Once cooled off, it took it on in. Now, it just doesn't want to run when it's warm and shifting. The temp gauge runs square on the quarter mark in the summer, this is up a bit. Last year, it hit nearly half going over Monteagle but gave no problems and went down on the downhill side. Also went down going to BS coming down the backside of the hill, which makes me think the cooling system is working. Both times it's quit, I pull the fuel line to the pump input, nothing there. Interestingly, the output line pulses when the engine's running. Going to Louisville, I pulled the air cleaner and pumped, no gas in the carb, but clear filter.
My thoughts are, it's vapor locking back down the line someplace, or the carb is getting so hot the pressure sends fuel back towards the tank. Or the pump is dying, or the ignition module gets too hot. I am however open to other ideas.
This weekend is committed to getting my 'travel truck' engine installed and it running. The toad isn't really a good commuter, it's missing many of the amenities like A/C, an automatic, etc. Once it's going, the GMC will get the tanks pulled out and checked, a new fuel pump, and a new ignition module. I'll keep the current module as a spare. Hopefully, all of this will highlight whatever's making the thing quit running.
