Cub Carb problem

Sat May 01, 2004 6:59 pm

I have a problem with the carb on my 1948 cub. It will stall if I don't have the choke about half way engaged, even when warm. The engine was rebuilt, but I didn't do anything with the carb and it ran OK for awhile. The adjustment screw seems to make little or no difference unless all the way closed. It probably needs a kit, but I thought I'd seek expert advice before ordering one. Thanks,

:?: When & how it stalls was not mentioned so I am wondering if it could be a governor problem instead of a carb problem :?:

If you haven't done it yet, pull the main jet and make sure it is clear. It is the one screwed into the outer side of the carburetor body.
