My carburetor gets hot and does this while driving it. I have a ply wood heat spacer and I have a 3 nipple fuel filter before the quadrajet and my carb still gets hot and vapor locks while driving. I have a new heat gasket like you shown and I have the room for it so I'm going to give it a shot and see what it does. I live here in East Tennessee and yeah it gets hot and humid here. Thanks for the video. Oh my ply wood riser heat sheild I made from 3/4 inche plywood. Just wish this car would stop vapor locking and leaving me stranded every time I drive it. I have a glass filter that I can watch fuel coming through and have proper heat sheilding fir the metal lines along with my 3/8 rubber fuel line far from the motor and heat. I have caused this down to my quadrajet. So hopefully this gasket will fix this problem. Thanks again

Thanks! I'm going to try one of these gaskets and see if it helps. I already have a phenolic spacer. I'm in Phoenix, 110+ degrees , 1966 F100, 390 FE engine. Drove 15 miles at 70-80 mph (2800 rpm), the other day. Ran fine. Got off the interstate and drove 1/4 mile, stopped at the stop sign and as I pulled out, the engine just died. Pushed the truck out of the way, raised the hood and heard the fuel percolating in the carb. An hour later, with some coaxing, it started up and I drove it on home. It was HOT under the hood, although the temp gauge wasn't higher than normal. There's no fan shroud so I'm going to add that, too and see if that cools things down a bit in there.
@EfurdGarage2 жыл бұрын
Fan shrouds are a must. The spacer should have done it but adding the gasket could help more. gasket is most likely better then phenolic at blocking heat although i never tested it. i run an aluminum spacer with the heat gasket on my daily in 100+ degree and never an issue so it should do the trick still

I have a 71 camaro similar issue you were explaining. Its starts great on a cold start even after sitting for weeks it still starts great. I will drive it for 15-20 minutes, get out and then try to start it again after a few minutes, it has trouble. It cranks for a good 20-30 seconds. It also stalls when I try go slowly up the driveway after starting it the second time. Can this be a vapor lock issue?
@EfurdGarage11 ай бұрын
could be, carb heat soak and vapor lock will be 2 different things. if you are running headers always make sure your fuel lines are rerouted away from heat since headers are know to be closer to the frame and they are a thinner metal then manifolds so there is more chance for heat soak which is also why a mini starter is a must with headers. I take ti since you say "up the driveway" its a decent slope which vapor lock would stop or slow fuel from getting to the carb so an angle could cause it to stall from not having enough fuel in the bowls. Now carb heat soak will boil fuel out of the carb and can do that as well. After its up to temp pull the air cleaner and listen for boiling. If you dont have an insulator gasket you should regardless many engines came with them from the factory and they do help. If you have a clear fuel filter before the carb it can tell you alot as well such as if you have vapor lock or a weak pump the filter wont have as much gas as when you started it, if the filter is full then its heat soak

Edelbrock carbs suck, especially with pumps with high psi ratings as edelbrocks do not like do well over 4 psi. edelbrocks are also not good for economy or power. The 109 lsa will also use more fuel do to the over lap, which sounds great but it spends raw fuel through the exhaust.
