Default engine run-on

hey-
just rebuilt my carb and i've had a few cases of run-on when i shut the engine off. it sputters very roughly for 1-2 seconds.

how harmful is this?
what are causes?

my timing was good and the engine ran fine before i redid the QJet. whatever the cause, it is right on the edge, as it only seems to run-on when the engine is very hot ie 200-210 after a heat soak from sitting for a few minutes and a short drive.

Not a big problem. Brake it with third gear and clutch.

Since you just rebuilt the carb, probably high idle or lean. Did you adjust both idle & mixture?

it does sound like an inexperienced driver failing to release clutch in gear
