Thanks again for the numerous ideas and suggestions regarding why my '31 V8 LaSalle will start, idle and rev, but within 10 minutes, at anything over 1/2 throttle (in nuetral or driving down the road) she stumbles (seems like runs out of gas) and dies. Then she won't start for at least 10 minutes (cool down). I am sure Ed is right...I likely have multiple issues. After checking / eliminating several items suggested, including replacing the coil, I'm beginning to think the primary problem is heat related. (Viv made some very interesting comments on the subject previously)
Does anyone have a suggestion as to how to eliminate (disconnect) the heat exchanger tying the Johnson to the exhaust manifolds?
My fan belt is pretty lose to, hard to watch from inside the car...maybe that's aggravating things.
I wonder if I can get any clues by using an infrared thermometer...I'm now realizing my temp gauge does not work. Any rebuilders out there?
Thanks so much for any help, I'm amazed at the generosity of time & knowledge.
