Torque on all bolts should be 150 inch-lbs.

Ok put everything back together early yesterday. Ran it today, nothing changed. Plug number 3 still has a load of white/grayish scum on it after running.
Anywhere else water could be getting in?
I know this motor doesn't have a head, but could the cover by the plugs have a leak in the gasket?

No the gasket around the spark plugs cant cause a leak into the cyl. I wonder if there is a crack in the water jackets somewhere from overheating or something.

Well, when I had it apart it looked pretty clean inside, not to mention outside it looks mint, but there could be a crack inside somewhere. I'm wondering if it just needs to be run hard for a while. I've only ran it on the stand (muffs) for periods of 5 -10 minutes, and it ran/idled fine. Takes a little effort to start, but thats common for these motors so ive heard. Figured out that I can pump bulb hard, give her some neutral throttle, hold choke and crank. After about 5-10 seconds of cranking, she sputters a bit, one more crank and she fires up quite nicely.

My dad said that I should just run it and not worry about it but I'm worried about it quitting on me in the middle of the river.

Where you ever able to fix your motor? I have the same problem with mine and I did what you did first as well and it didn't work. I have been to busy the last two years to get back to it so it is still sitting in my garage in pieces.
I have been anxious to get back to it, but I am not positive what to try next.

You are camped on a two year old thread, start a new thread with a description of YOUR problem.
