I have not touched the timing on any of these repairs. I've only replaced the valve stem seals on these repairs.

I understand the synchronizer to not have to be "timed". It can be stabbed into the engine at any degree since it's the sensor that receives the interrupted signal and not the gear on the synchronizer. The 15 degrees that the manual states is used only so the sensor wiring harness will be in the correct orientation and not be stressed when it is plugged in. Granted, the #1 cylinder should be at TDC to do this.

Actually the rocker arms were removed the whole time I was doing this so the valves should have all been closed.

If all of the valves are closed, that's why it won't turn over. No place for the compression to go.

That's what I was thinking as I read his last post.

Trust me on my 2cylinder John Deere... you cant even begin to try and throw the fly wheel if the petcocks aren't open.... too much compression. (Guess that's a good sign I have a strong engine tho lol)

white89gt

Agreed, that is a good sign.... or at least it's not a bad sign, LOL.

Spark plug hole?

white89gt

No... the valves are closed. How is the air going to get out the plug hole if the intake valves are all closed?

Didn't you say you lost a valve keeper while doing the seals? Did you ever find it? That would of been enough to keep the engine from not doing a 360 turn.

barecycles

Never did find it.

If there are no rocker arms, all of the valves are closed. No place for the compression to go. I guarantee this is his issue.
