finding TDC (technique)
i believe that my balancer is spun(seperated), so the timing mark can no longer be used :nonod:
my kid and i were trying to use a screw driver in the #1 spark plug hole to see when piston travel stopped, but found it not very acurate.
anybody have any other ideas?

Re: finding TDC (atotalnincompoop)
See if you can find a bolt with the same thread as a spark plug or pick up a stop indicator at an auto store.
I assume you've pulled all the plugs to make turning the crank easier.
BTW, if the damper bolt unscrews when turning it backwards, install three long bolts into the three pulley holes and use a pry-bar to turn it.

Re: finding TDC (atotalnincompoop)
It needs to go in far enough for the piston to touch it, or "stop" against
it. Then, what you do is turn the crank until the pistons "stops" against
the bolt or stop device, and put a mark on your balancer relative
to some point (like the timing tab). Then, turn the crank around the other way
until the piston goes down and comes back up against the stop and then
put another mark on your balancer aligne with the same reference point.
TDC will be half way between your two marks.
