Dave what about wear in the baseplate with the throttle shafts? Sometimes I have seen the return spring on the bottom of the pivot linkage with the accelerator attached at the top.

The better design is to put the spring in line with the accelerator cable (attached at the same point) so it pulls directly opposite of the accelerator cable. It will be a vacuum leak in the carb or a timing issue as previously mentioned. Now, if you had Webers............
