A couple of days ago I bought a 1942 Welin lifeboat with a Kermath 8-10 in it. The motor is complete, rolls over by hand and has spark. It's been sitting for 40 years and needs some help. The exhaust valves were stuck, I got them freed up. I opened the tappet cover and did a cursory adjustment (they were way loose) and got her to "sneeze" at me a little. Where should the spark advance lever be to start it? Is it possible to start her by kicking the flywheel over? Does anyone have a manual? Any help would be appreciated. Thanks in advance

I'm not real familiar with your motor so I can only offer some general advice. The timing should be retarded for starting, especially if using a crank. Does the mag have an impulse? Is it automatic or do you have to latch it in every time you crank? The impulse retards the timing and helps prevent kick back when cranking. Is the compression good? it will generally increase after running. If the valves were stuck open it's possible the seats are rusty. I doubt if you will be able to start it kicking the flywheel, possibly after it's been running it may start like that. Do you have a crank for it? Usually you would set the crank so you can give it a quick pull over compression.

I got the motor running yesterday. I went and talked to a freind of mine and he said he sets his old John Deere tractors valves at .20. I primed the cylinders and started rolling it over with my foot and the next thing you know the neighborhood was clouded with smoke from all the oil I poured down the jugs. I ran a couple of float bowl of gas through her and now it rolls over freely with plenty of compression. How does one change the oil in one of these?

Auto parts stores sell manual operated sump suckers that will pull the oil from the base and push it into a bucket.
