whining from engine?

And your sure you have all vac ports plugged? Any slop in throttle shaft/s? what kind of carb you running? You oughta take a Vid, cleaner off and run throttle up slowly. Try spraying CRC mass airflow sensor cleaner around carb shafts, base, and intake manifold edges, see if it effects running.:clock: Some carb cleaners might melt paint. let us know:happy10: Oh, and your not running a gear drive right?
