The engine haven't been run for a while.

Doesn't really seem to matter through with this engine. I think I got enough info on it with a compression check and a cam check.

First-#1 intake valve doesn't open all the way-> worn cam lobe. Rest of the valves open ok.

Second - Compression check (cold and dry) - 80 - 128 - 152 - 142 (not worth doing a wet check).
- I assume the low compression on #1 is due to intake valve not letting the engine breath correctly.

I guess the conclusion would be that this engine is worn out.

I did get the M410 (the 1800 version) with the engine, so not a totally lose.
