So this year when the weather got good it was time to fire up the car. I have a 65 vert. 4 speed. with the 401. The car started and idled just as expected. After it warmed up, I took the car for a ride and it ran very rough, (fuel was treated for the down time during the winter). I thought I was having carburetor issues and took the Carter AFB off for a rebuild (long story here, so I'll fast forward some). I kind gent from this site was generous enough to donate a carb to get me going again(Carter AFB). I put that carb on and it idled better but when I put the gas down it ran very rough in the secondaries.. I checked the timing and it tends to run best at 15 ATDC, which is a lot compared to the original specs. (new plugs, new wires, new cap, Petronix under distributor, new coil, no vacuum leaks.) I was told the car sounded like it had a different cam in it as if the motor was built up. I have no idea what the inner workings are in the engine. Any advice is welcome. Thank you in advance.
