Combines Engine overheating

[lbran]

What have you done so far. ie: checked radiator and hyd. cooler for cleanleness, is outer screen turning when engine running. Have you checked the timing on the engineIJ Advanced too much will cause temp to rise. let us know what you have checked, and what you found.

Is the carb set correctlyIJ Way too much gasIJ Black smoke out the pipeIJ Or the other way. Way to lean. Jeremy

I was thinkin' the same thing - maybe carb is set too lean. If exhaust manifold is glowing, sounds like that could be a good posibility. Tom langan

exactly, used to find this a lot. 71193453 is a no 75 jet. use a jet bit and open it up to a 77. this would be one jet cleaner bit larger. But first make sure it is ClEAN and no rust or goop in it and all filters and lines clean and float level is not too low as this will run her lean as well..

At times the point cam in the distributor will rust tight to the distributor shaft. Remove the cap and twist the rotor in the direction of normal rotation, it should rotate about 10 degrees and snap back to the original position when you release it. If it is stuck or stiff you will not be getting any spark advance which will boil the radiator and turn the exhaust red real fast. With a timing light on it you should get 15 to 25 degrees advance from idle to top speed.To free it up put a good solvent oil in the hollow rotor shaft and use a small vice grip to gently work the advance unit untill it works freely. The shaft should have a little felt pad in the end of the shaft This pad should have a few drops of oil every year to keep this shaft oiled. nobody seems to think of this , so they get dry and stick in the off season.

Rotor Man: You have hit the nail on the head. We had a customer with an F2 with the 292 gas engine last fall that had the same thing happen for exactly the same reason. We freed the distributor advance and checked the timing and the problem was solved. Have a good day.
