vapor lock / carb boiling in the bowl how to tell diff? - 06/16/08 07:36 PM
My 65 dart /6 with a 1 barrel Holley has had what appear to be vapor lock problems. I've recently learned that boiling in the bowl in the carb is similar.
How do I tell the difference when it is happening?

not sure but the /6 heat risers divert WAY too much heat.I would turn the counterweight "off"(I forget which way that is) & lock it there.

I knew they were the same thing but different locations. I want to know how to tell the difference since they would require different fixes.

My experience with boiling in the carb is that you can hear it boiling a minute or two after engine shut down (at least on a small block).

Not to hijack, but my buddy has a '65 A100 Pick-Up with a 360/727 and a Holley 4bbl.
When driving all is good. Sitting in traffic (Woodward DreamCruise) the engine starts to bog and will stall, but will immediately re-start. As long as the rpms are higher it's OK. Put it in gear (auto) and it bogs and stalls again, and the process repeats.
He has shielded the fuel line from the pump to the carb, added header wrap, and created a fan shroud to no avail. Don't know if he has the intake crossover blocked or not (he purchased the truck as a turn-key). Does this sound like vapor-lock? If not what might it be?

are you running "gasahol"(10% ethanol,90% gasoline).
