Well, there is only one mark on the balancer. So I have no choice but to trust that its correct. As for procedure, I unplugged the timing wire and set to 0º TDC. Am I missing something?

Sounds good!

if you suspect a timing leak and can't find it, might have to borrow a smoke machine, that's the best way to find 'em.

Yeah them timing leaks are a bugger to find without a smoke machine...

I'm on enough pain meds it made sense too!
