Luke, those oilpulls should run cooler on gas than kerosene. I think there is an other issue there if it is actually over heating. Frequently the hub in the cooling pump impeller is worn loose on the shaft, most of them are just cast of aluminum and soon Quit driving when they come loose and of course you loose circulation. An other issue that crops up is often the pipes to the radiator are cut too short and over the years a lot of packing gets forced into the fittings and radiator spacing rings till it plugs them off. Of course pistons fit with out enough clearance will score. Just some more home work for you

Darn I missed the plowing on the g. But glad I wasn't plowing when piston scored.it looked like the ground was a little wet to plow. Looks like a busy winter for you
Dan. Ps really nice meeting you and your family at rollag.

Should reword this to read, "Those Oilpulls can still operate on gasoline when the engine happens to be cooler. Operating on kerosene will not cause the engine to operate hotter." If some of the kerosene didn't burn, it could provide some slight lubrication.

I stand by the original wording of my post.

Ive ran a 20-40 lots with straight regular gas and it run nice and clean. Only issue I have is I had to bypass the fuel line around the heater in the exhaust or the gas would boil coming into the mixer. I think unburned or partially burned kerosene would cause carbon. The impeller on my oilpull came loose years ago if I remember correctly it just had a pin through it. I put a bolt and locknut on and been good ever since.

We had an impeller come loose like that on an Heider C also and of course it caused overheating.

Halcon;
I was referring to your first sentence only on my suggested reword. Other portion, I agree. Sorry about misunderstanding. Ed

Timing out will cause an engine to run hot.

I got the motor off of the cribbed boards. I made a steel frame to set the motor on and set her down. the way the plumbing is on the bottom is simple but complicated to disconnect. there is a jam nut on the right jug that needs to be loosened, then you thread the cross pipe out to loosen from left jug elbow, and threads further into the right elbow, when threaded out enough then you can take off the left and right jug. uffda, a good flange mount would be a lot handier..

jugs are going off with pistons to get sleeved, pistons will be turned down to match the sleeves.

[lukeste]

The jugs ar in the boring bars now. Each side will be sleeved. They will be dry press fit in. The pistons will be cleaned up in lathe and address ring lands at that time.
