I will put the wires back in their orginal spots and start over because the running condition has been worse since moving them. Try something else? Would anyone recommend repositioning the dist.? Which direction, to the right or to the left?

you dont need to move the wires if you timing light show 8 degree then it dont make no dif where you got #1 at in the cap 8 degrees is 8 degrees. you move the wires back and set the time at 8 BTDC then its the same thing. 8 degrees should not be to hi
