Read carburator cleaning by (jbla) Lazy mans TK carb. Checking into the cleaning of carb, checking spark plug. But 1st, I leave work, 4 mile trip. Get to store, engine off. Come back to try and start up. It will not. It is as if the carb is hot and has vaporized the gas or the float is stuck in a position. Tap bowl and play with the choke, 1/2 position. Finally I can get it lit. So much for side trips on the way home.
