:shrug: I have no clue, could be something wrong with any one of the things you have added (haven't had any good luck with champion plugs), go back to where it was last running.

When you set the cam (gears dot to dot) #1 & #6 pistons will both be up, But cam will be set for #6 to fire. Try setting distributer for #6 to fire. Richard |

From front to back 1 2 3 etc firing order is 1 5 3 6 2 4. It is distributor going clockwise number 1 is at about 4 o'clock position. Richard |

yes all correct.still backfiring,not sputtering ?not even running enough to play with.if it does make a difference.i did do cap n rotor and a msd ign coil.ballasts are new .power reg is new.i did 8 mm marine wires with champion plugs.think its too much? i have a double barrel carter too.so i think itl run sweet once i figure this timing problem out. jimbo p.s it also has a aftermarket cam .dont know wat it is ,i didnt put it in |
