sorry for the delay on the reply, the weather and time off isn't aligning up. i think i have learned a lot about the vaccum advance by reading some old posts on this site. i see why it would need to be disconnected so timing is not advanced with the rpm's. i don't fully understand why it needs to be advanced at higher rpm's for proper ignition but i guess that can be reading for another time. i made a tdc tester out of a old spark plug. i busted out the ceramic and slide in a old push rod and welded it in place. i could slide a small rod down in it thru the push rod. as i turned the motor the rod rose then drop. so i found out that the balancer is right- best i can tell. when the piston is at tdc the mark is at zero. the cam is stock and dist. has never been out as far as i know.i tried what twisted6 said to and took off the cap it looks to me that it is pointing between 2 and 6 spark plug wires. so what does this mean? how could it even run that far off ? is it 180 deg off because its on the exaust stroke and if i turn the engine a complete revolution will the dist. move 180 deg? its still not off exactly 180 so i guess it could be one tooth off if thats the case. i will mess with it again the next day i have off. any more advice would be helpful thanks for all that has been given. hoggyrubber
