Hello all.
I'm working on a 1962 770 gas. The issue the tractor is having is that it will not idle at any speed below 825 rpm without having the choke about 1/3 closed.
I have cleaned out the fuel tank, sediment bowl, and fuel line to the carb. Pulled, cleaned, and soaked the carb. Cleaned and blew out carb and re-kitted. Problem still persists.
Sprayed ether around the intake and carb, but did not get any change in engine speed.
Checked power to the coil, wound up replacing the wire from the ignition switch to the coil, as well as the wire from the coil to the points.
Installed new plugs, wires, cap, rotor, points, and condenser. It runs a little sweeter, but at the same 825 rpm, it dies just like you turned the key off if you open the choke.
I have tried to find out what the resistance readings for the coil are supposed to be, but cannot find a thing. I have measured the coil primary and secondary windings both cold and hot and have the readings recorded.
My Dad has a '61 770 that does something similar, but only when it's warmed up. This one does it all the time. I also measured Dad's coil. The changes in resistance on his are opposite of the changes on this '62.
Both of the coils get nearly too hot to touch after running for 10 minutes. Is this normal (because they have an internal resistor), or is this a sign that they are bad?
I can post the resistance readings for anyone that would want to know what they are.
Any pointers would be greatly appreciated.
Thanks for your time,
Luke
