Thanks Kev, good tip about sanding on a flat surface. I'll keep that in mind if it happens again. Didn't seep from that gasket today during testing.
Last night I took on the exhaust leak. I undid the downpipe, and removed the first exhaust hanger (to allow me to better line up the flanges). I cleaned off both flanges the best I could, then applied exhaust gasket sealer to both sides of the new gasket. This stuff: VersaChem Exhaust Seal. I tightened in an alternating pattern until everything was snug. Let it sit overnight to fully cure. Zero exhaust leaks today.
Today I removed the jets and the gaskets, then made new ones from a sheet of gasket material I had from NAPA. They worked perfectly, no more leaks. I also cleaned up the threads on the fuel line to carb connection, applied some fuel safe thread sealant, then carefully tightened. I let it sit for an hour before testing. No leaks at all now.
I let it warm up in an attempt to dial in the carb, but I'm struggling. I just can't seem to get it right. I can hear the engine stumbling and it just isn't as smooth as it should be. Snappy throttle, but the engine shakes more than it should when I give it power. Maybe it's harder to dial in when it's cold out?
