Trying to figure out what the blip is on the hand held tach and you can hear it as well. Keep in mind aside from the little fluctuation on the hand held tach the car is running perfectly with no other symptoms or reactions.
Intake manifold recently sanded flat, Carburetor placed on a piece of glass and appears to have a flat base, carb dismantled cleaned and reassembled after 11 years and 1800 miles, just in case, new intake studs installed, new fat gasket with Hi Tach gasket dressing installed, new brake booster so no problem with the check valve as the new booster has the check valve built in as part of the unit and I sprayed a half can of carb cleaner all around the carb and the intake manifold with no signs of a reduction/change in power - car is running great but that little blip bugs me, you know..... I have also installed a new valve cover gasket - all components are in place, that is, the snorkel cover, the two rubber hoses from the engine to the carb one being the lower connection of that small hose to below the carb. I guess I know that it has to be a vacuum leak but just hoping it might be something else as I really thought after all of the work listed above that the car would in fact purr like a kitten - like I said earlier the GT is running really well with no noticeable issues at any speed with the exception of that little blip at idle, which unfortunately existed prior to the all of the work mentioned above. Thanks, Carl
