I’m beginning to think this Hemi may never see the road again. Last time I started it, one of those plastic fuel filters ruptured and sent gas everywhere. After replacing those and finishing up some other work, I tried to fire it up again today - only to have the front carb leak all over. Thinking maybe a float had hung, I carefully removed the carb and set it on my bench and removed the top. The floats were hanging OK but any jiggling could have loosened them. Fuel levels in the bowls were not high but the gasket was wet and fuel seemed to be coming out the shafts and various bleeds and every where under the cover.
Then I noticed the AFB secondary air valve wells had fuel in them as well as other places the top gasket should seal.
The cover screws were snug but not especially tight at all. I just rebuilt these carbs a couple months ago so all new gaskets, needle/seat, accelerator pump, etc in them. They were not leaking before rebuilding. I can’t see anything else out of place so all I can figure was the top was not tight enough to seal. The seats are tight and gaskets in place. Needles look sharp and clean. This is the front carb and since the engine was running on choke and fast idle, the front carb was just idling. Once the fuel bowls were filled to set level (and not flooding) and the needles seated where could fuel leak from under the top cover and end up everywhere????
I guess I’ll put it back together and make sure the cover is down tight and see what happens. If anyone has any ideas on this please share them.
