Re: Tuning Q after a tear-down ordeal...
I just received a suggestion to drop the bolt off the balancer and look at the keyway location on the hub vs the TDC mark. Apparently if the keyway is pretty much in line with the TDC mark I time off the 2 o'clock position. If the keyway is offset by "an inch or more" then I time off the 12 o'clock position.
Anyone think this is a legit method? I'll take a look at this tonight just for the heck of it. Having trouble finding timing covers in stock locally.
I'll also be pulling the valve covers to replace the crap gaskets I got last time. So I'll make sure that TDC is accurate and both valves are closed on #1 just to be sure.
EDIT: I'm going to make a piston stop out of an old spark plug and turn the engine by hand to ensure the TDC mark on the balancer matches up with the tab and actual TDC. If not, I'll mark a new TDC location on the balancer using the existing tab. Thinking that I am going to mark the pulley as well since there's a chance the balancer ring is slipping. Just learned this trick, seems like a reliable way to be certain.
