How to fix a high gear miss like the one in your video.

#1. Get off the internet, leave the beer in the frig and get to work.

#2. check the valve springs. If you have an inner spring broke it might not miss free revving or in low gear. If you continue to screw around your motor might die a painfull death of parts crashing into each other.

#3. Remove the fuel lines at the carbs and do a gallon jug test. See how long it takes to fill a gallon jug with your fuel system but make sure you pull the lines at the carb to fully test the system could be a collapsed line. Like someone said unless your regulators is rear of the front spindle you can get away with 3 psi. I have never needed to run over 7 psi.

#4. Borrow an ignition tester. Even a mopar unit can be tested with an MSD ignition tester. Someone close to you should have one.

#5. Throw your fuel out and get some fresh
