Been focusing on the carb, but now I'm wondering if it's crank seals...New diaphragm, flap valve, little bit-o permatex...
i did in fact officially give up. Gave it back. The old man noticed as the engine sputtered, that the exhaust was leaky.
He said, "well, I'll put new gaskets on that". Well that got me to wondering, could that be a running problem ? I wouldn't have thought so, but....
