hunter: thanks for the link
turbo: yes it stopped by itself sort of.

My search feature isn't working. I had previously read that link before and was searching for it. I was glad I had read it. I ended up putting a bottle of brake fluid into the intake which starved the air a bit, but as previously stated, the intake was leaking from other areas and the engine kept running.

I believe that we took the oil level down to about 1/2 between the notches on the dip stick, and that I caused the runaway by overfilling the crankcase a bit.

I'll start a new post, but would like to get 2 things sorted on this engine.
1. an emergency shut down device like I have on the throttle of my 300d turbo.
2. some photos showing the vaccuum line plumbing as it exits the fire wall into the engine compartment. I've got a mess of spaghetti there from previous owner. Lots of disconnected vaccuum lines.

thanks in advance.
Mike
