Marty SNAIP John, I said it was an Edelbrock, but it's actually a Carter 750 manual (Carter and Edelbrock, it's my understanding, are clones). Do they have a power valve? How is it checked? I did have the carb off several times adjusting and rechecking the float levels so I will check that also. Thanks. Marty SNIP That you did, my error I read what I wanted to read now what you wrote! Sorry about that. Carter/Edelbrock do not use power valves there for do not fail. I never had a problem with a Carter/Edelbrock surging so am at a lost as to what to suspect right this min. Apologies, if I think of something else will drop a line. John. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
