am having a problem with my old Wiconsin aenl engine

It starts just fine when it is cold -- idles just fine for up to a couple of minutes and then dies. will not start again until I wait a couple of hours. then the same thing happens

I recently put a new head gasket , and rebuilt the carb and when it does start up it sounds good.

I think I would start by replacing the condenser. Sounds like it could be getting warm and shutting things down until it cools down.

I have had the intake gasket (between the carb & the engine) cause similar problems on a Briggs engine.

This has been bugging me all day. Actually, my answer has bugged me. It wasn't the gasket itself, but the mounting bolts. As the engine ran & heated up, the bolts would come loose and it would suck air around the intake gasket. A little blue Locktite solved the problem.

I replaced the condensor and points but it still happens. Starts right up idles fine for about 90 seconds then dies out.

I do I check for a vapor problem?

try loosening the fuel cap,vent might be clogged. it sounds like it dies out too fast to be a heat related problem, i would hang a small tank iv style straight to the carb and bypass the original tank and lines,if it runs for five minutes you know the problem is between the carb and tank,if the gt has been sitting a year or more i always pull the float bowl off to check for water and varnish and for needle and seat fuel flow function. best of luck. :thumbs:

Those would have to be some awfully loose bolts!!!

It might be it's running just long enough to run the gas in the float bowl empty..
