choke trouble
ok so here is what i found, i took off the choke thermostat and checked it out it dint't seem to be messed up but didn't seem to be assembled correctly. so i cleaned it up a little and put it back on and checked the hot air intake tube and it seems fine. when i put the thermostat back together and adjusted it my choke was opened up about 1/4 or so and it fired right up and sitting in the cab watching the temp and reving it a little you could really feel a difference in the way the pedal felt. but then as it got up to temp the choke did not o[en it was still at about 1/4. thats where i am. isn't it supposed to be open all the way then it's warmed up? any ideas?

I don't know about your choke, but my electric choke is adjusted by turning the choke cap one way or another to put more or less tension on it.
I wanted my choke to open as fast as possible (because previously I was having trouble with it staying open), so I put the cap in the freezer so it would cool off since I had already tested it with a 12v source and it was warm.
After about 30 minutes of cooling I put it on the carb and turned the cap so that the choke butterfly valve had the least amount of tension on it, but still enough that it would completely close without play. When doing this you don't want the carb stuck part way open for the high idle, you want to "pump" the throttle so the choke can close all the way.
I later turned it an extra 20 or so degrees to give it more tension, because if the engine had sit several hours and was just barely warm.. the choke was still open and the engine needed it closed this time of year.
