Hi
So, I have a 52 side mount, with MS carb. Just rebuilt engine, rebuilt governor, replaced fuel shut off bowl contraption, bought rebuilt carb, replaced wiring (except plug wires). Was running okay, still didn't seem perfect, then I shut her down for a few weeks. When I came back this weekend, found out I had left the key on. I got her to run, but only with choke pulled out, which I took to mean I about killed the points. So, ran it for a little bit, then she struggled even with more choke, so shut her down for the night and replaced points/condenser this morning. Ran her for half hour to hour or so. Still wasn't seeming quite right, and thinking maybe some bad gas, I went to get more gas. When I got back, gas was leaking from the carb. I swapped that carb out for my old carb, ran it another half or full hour but then when stopped saw gas leaking out of it. So, I swapped back to the newer carb, and pushed the metal fuel tube up a little bit (as I thought I pulled it down some when swapping carbs). Instead of wait to see if this was going to leak again, I just got her running and mowed the rest of the yard. About an hour into it, seemed like the rpm's started dropping, then up then down. Not terribly bad, but didn't seem right. Then I shut her down. When I shut her down I turned the fuel off and let it die out, so that I wouldn't have to deal with leaking fuel, assuming it was still going to leak. I could hear air bubbling in the gas tank once it died (maybe normal, I don't usually shut her down this way) .It was also leaking what may be gassy oil at the oil line convergence area behind the exhaust clamp. I'm thinking maybe I got gas in the crank shaft and that's why this connection is leaking all of a sudden. Smelled like gas, but so did my hands, so not 100%, nor was oil level excessively high (or noticeably higher).
So, any thoughts on what I should tinker with next? I saw online that leaking carbs are typically stuck needles, etc, but just seems odd it would happen with two carbs in a row, granted the second one was not restored yet.
Thanks for any suggestions!
