I will check the accelerator pump tomorrow. The base gasket came with the carb. and the notches line up with the pin hole in the bottom of the carb. They do not line up with any notches in the insulator...should there be notches in the insulator? My old engine had them.
It does not do it any other time than when I hit the throttle fast from idle. It does not seem like a vacuum leak but I suppose it could be.
I will also contact service at Holley. The carb came with a warrantee and a service number for troubleshooting. They are not open today and the stovebolt always gives me good advice.
BTW the engine does not hesitate when this happens...Can I assume that this is a good indication that the accelerator pump is ok???
