Hello,
I just rebuilt the carb on my Ford 860, installed a new gas tank (original tank had a pin hole leak), a new fuel line with a heat sleeve, & a new vented gas cap (free replacement from the 1993-10-T2 Service Bulletin). The tractor runs better now, it'll idle for long periods (30+ minutes) with no problems. However, when I increase the RPMs, it seems like it's getting too hot and eventually stalls. The collant temp is below 200 degrees. After it cools down for 5-10 minutes, it starts right up and works fine... for a while. It had a similar problem before but I assumed it was due to flooding since gas was dripping from the carb each time it stalled, which doesn't happen now since the carb rebuild.
So, what could be causing this problem? The antifreeze is clear and at the proper level. My dad flushed and filled the radiator before I got the tractor so I assume it's 50/50 but I don't have a hydrometer to be sure, I guess it could be 100% antifreese. The fins are clean and as straight as I could get 'em. The water pump seems to be in good shape, no wiggling or odd sounds if you move the fan blades. Could it be a bad thermostat?
It might not be overheating, it could be something else but it seems like a lot of heat is coming off the engine after it stalls. Any input would be greatly appreciated.
