Guys,

Thanks for your response.

Didn't damage the valves turning by hand.

Here's the weird part, with the head off and observing the piston on #1 and the timing balancer position at O/T mark it does not put the piston at TDC, rather a bit lower.

However if we move it to where the magnet is located, the piston is now exactly flush with the top of the block?

There's something I'm are not getting, the manual is very clear on the positioning for mechanical timing?

At the O/T position it taps the pistons? At the magnet position its clear of the pistons.

Whats going on.
