Hi, I have a 1968 3hp Lightwin. It's been a sweet motor and I really enjoy booting around in it.
I was getting ready for the first trip of the summer and put the motor in my test tank... and it got super hot. I wish I had been watching it a little closer, but I'm pretty sure it's okay: no discoloration or anything...
I checked the impellor, it was fine. I searched all over for a thermostat only to learn there isn't one. So I took off the head and exhaust cover and found it was plugged right at the passage you can see from the exhaust side that enters the cylinder cooling jacket. So I think that's problem solved there.
But here's the thing: on examining the cylinder jacket I don't see how the water is forced around the jacket to the water outlet, rather then just going straight from the inlet to the outlet (They are right next to each other). On newer motors I know there are these little rubber "thingy's" that insert into the jacket to force the water to go around. Am I missing something here? I don't see anything on the parts diagram.
Please help. This little engine is way to sweet to have a idiot like me wreck it.
Thanks in advance.
