I have a 73 GMC Truck. It runs fine until it gets warm then it cuts out and dies. What would cause that?

Answer 1

Check your fuel line that runs next to the block up to your carburetor, if it is too close to the block, then it will heat up the fuel line and cause it to vapor lock...I had that same problem once on a 72 ford and it solved the problem

Answer 2

Most '73 GMC's have a thermocoil style choke mechanism on the carburetor. This could be electric or not but that's your culprit. First try to open it up and clean, lube, and reset it. If this don't do the job, then the thermocoil itself is shot. You're going to have to get the identifying numbers off of the carb and go pick up another choke unit. They're not very hard to install and set. All you'll need is a pair of needle nose pliers and a screwdriver. It'll come with a step-by-step in the box.
It wouldn't hurt to run a bit of carb cleaner in the next tankfull either.

My house is seldom warmer than 60F. correct now that is, (57F, 14 C) and that's on account that is a gentle day! i'm dreading the chilly climate being anticipated for the weekend! the only reason i'm putting forward it incredibly is that i'm hoping somebody would very nicely comprehend that i'm no longer the only one suffering like this and that i'm beneficial there are a number of greater worse off than me. that is not any longer hassle-free sufficient being 'ripped off' by ability of the super oils companies and extortionate government taxation, yet any so-called 'eco-friendly Taxes' will in basic terms make it worse for persons like me and might have not have been given any impression on the organic technique of world climate cycles.
