Low Compression After Rebuild

Heads were micro-fluxed, valves 3 angle grind, re-seated, new seals and adjusted by a machine shop.
I've double checked the clearances, they're in spec.

Ok gents.
TDC, timing mark pointing at 0, rotor pointing at #1 spark plug.


Found this, needs to be fixed for sure.

How they were when I first took the motor apart.

Flipped and torqued, 80ft #s

Tool shot, my home made sprocket tool, bottom right, works very well.

After install.

Left sprocket, marks line up great.

Right sprocket, here's what I meant when I stated the marks are a little ambiguous. Mark won't line up perfectly, mark lines up a little behind or I could set it a little ahead, but not dead on.

I'm holding at this point to see what you guys think, set mark behind like it is now, or move it a tooth ahead ??

Looks to be a tooth behind. IIRC, the timing mark on the sprocket will be in the exact 12 o'clock position when everything is lined up.
This may help.

Thanks for the FSM link, I downloaded one from a different site, it was in RAR format and I wasn't having much luck getting it to open, your version is in PDF, sweet.
Looks like I'll go button things up and see how she runs, take care of the cracked hose too.

It's a brand new Gates belt, bought a full timing component kit.
There was no way I was going to re-use the ITM belt it had on it.
