Unhook your fuel line from the carb and stick it in a 5-gal bucket. Run pump and use a stopwatch to time how long it takes to fill the bucket.

Post results back here tomorrow before 4:00 PM Eastern, I have something to do after that.



do the fuel flow test first. You have 2 fuel
related issues
1) vapor issue which most likely is just the gas
you buy. Right now you are buying winter grade fuel
which has a RVP of about 15psi for easier winter starting
(when temps are real cold) but if the temps warm up
it boils very easy also if it has any alky in it it
boils all the easier yet, Summer grade fuel has a
much lower RVP of about 8.5 which doesnt boil as easy
2) You have a supply issue, your fuel gauge showed
you this... it dropped to 1 psi.... do the flow test
and if it shows low start working backwards toward
the tank looking for any kinks in the line or any
blockage
