Idle Problem
Guys, I have an idle problem when I restart my 80 L48 when the engine is hot. The car idles normally at about 800 RPM rock solid in all conditions except when I restart it after turning it off for a few minutes. It will idle rough for a couple of minutes and even want to stall until it seems to clear itself out. The carb is bone stock original and has never been touched even the idle adjustment screws are still plugged. Any ideas?

I had a similar problem with my 81. Before I bought the car it set up quite a bit and wasn't driven much. I bought a can of Berryman's B12 carb cleaner in the spray can. Started the car and sprayed directly into the bowl vent, the small open tube at the carb air intake. I continued, occasionally running the rpm's up until the can was empty. That solved my problem without tearing down the carb. I think the carb was just gummed up from not enough driving.

It's possible your fuel well plugs may be leaking a bit, causing an overly rich hot restart, which otherwise wouldn't be noticed on a colder restart when a richer mixture is desired anyway.
