Did you change the cap and rotor too? If so is it oriented the same way the original was? I just went through this with mine. Started it one day and ran like shit .. knocking really bad, the whole bit.

I changed the plugs, wires, cap and rotor and still was really bad ... to the point where I thought I may have spun the main bearing!

It was then that I noticed the cap was 90* different than the original in that the #1 pin was not where it should have been. I rotated the wires 90* from stock and it worked ... runs smooth now. Aftermarket cap ... go figger.

Anyway, the whole point is that if the cap and rotor have gone too, it won't run right no matter what you do. Be careful if you get a replacement though and make sure the pins are oriented the same.

Dunno if that helps or not.

A broken valve spring can have similar symptoms but I'd be checking what lornix said first. Sounds like an ignition problem.

check to make sure the metal thing lol inside aren`t loose and yea some of the after market caps will fuck ya around, did the same thing when i put a new cap and rotor on, flipped it around and good to go,

You sound like a pretty scary guy with a wrench. "Timing shaft thing"? Maybe you shouldn't be messing around with shit until you understand how it works.
