Truck Name and Overheating

[Phil Waterman]

Well my Pattern 12 C60L is formally on the road and finial has an official name, hope that our group will approve of the “vanity” license plate my other trucks have carried the license plates BEAUTY, and BEAST the new truck has the plate CANADA.

I tried to get the truck on the road for our clubs big summer rally at the end of July ( http://www.cckw.org/mvmvc_weare_rally.htm ), even headed out with CANADA only to have it loose power and overheat 10 miles from the home. After it cooled down, headed back home only to have it overheat, again this time called for the flat bed and hauled it the rest of the way. Part of the problem was the outside air temperature was low to mid 90s so I was over heating as much as the truck.
The overheating was a bit of a surprise as the engine had about 50 hours of run time on the engine stand but the engine was also intermittently hard starting. Checked the normal easy things, fuel pressure, and timing. Then started check the more difficult things thermostat, back flushing the radiator, would not be the first time that mice decided to build a nest while the radiator was waiting to be installed. Found nothing then because of the intermediate hard starting figured I would change carburetor. Before putting a new carburetor on thought better check the float setting on the new carburetor and discovered that the float was set over ½ inch instead of the 3/8ths listed in the CMP manual, so figured I recheck the carburetor that was on the truck it to was set over a ½ inch. I figure that this was causing the carburetor to run lean. As over heating and hard starting were worse when the truck was nose up, on hills figured maybe this was really starving the engine for fuel. After reinstalling the carburetor hard starting seems to be gone and the engine is now running cooler, only a couple of long road runs with lots of hills
