Bitter learning curve. Absolutely DONE with carburetors!!!

Demon,... Sir you have shown the light. You are right, I never considered that the fuel could have come from the pump diaphragm, that is one of the only things I reused, it was new but it did sit for years, and I shouldn't have used it.
Flex-plate bolts were torqued and I used threadlocker, so not likely unfortunately.
I still don't consider this a fail, it's been on my bucket list since I was a teen and I rebuilt this myself, all the internals are right and it makes tire smoking power. That is a win! A small setback because of an external part that I did not put together isn't enough to call it failure. I will rebuild, but this time with fuel injection. Then I don't have to learn all the settings, adjustments, choke, jets, secondary's, etc, it is operator error here, but in this day and age I don;t have to learn it.
