when putting my carbs together, i switched over to Grose valves in the float chambers.
when trying to install my valves they would not allow me to put a washer under the valve. when i did, the valve (thicker than a normal needle valve) would keep the pin for the float from being able to slide in. i ran them up tight and all seemed well. until... i fixed my fuel line leak. (see older thread)
maybe the extra pressure or the fact the bigger leak would bleed off the pressure... now this leak. this is an odd leak in a way. the valve cuts off the gas and only leaks when the fuel pump runs for a bit, like running the car. if i just turned on the key, let the pressure pump up and let it sit, no leak. but when running the car, i was getting enough extra fuel to eventually come out the overflow. And it would continue until the pressure bled off. i was thinking i kept getting dirt in the valve or it was bad.
in other words, i thought the leak was thru the valve but it seems it was around the valve. after pulling the valve back out a couple of time and trying it, i installed it with aviation sealant around the base. seems to have fixed the issue.
just FYI. i know i have read threads where people were complaining about these valves leaking. i wonder if they had the same issue of leaking around the valve not thru it.
