[AT] More engine issues

[Charlie V]

"A motor that runs good cold [ without the choke ] is not going to run good
hot. A cold motor needs lots of gas droplets in the combustion chamber so
that the individual gas droplets burn somewhat consecutively and the motor
runs somewhat smoothly. Once the motor gets hot the gas in the combustion
chamber flashes to vapor and burns very well unless you have too much then
it misfires."

This statement makes a lot of common sense and also explains why the
old tractors could not run Kerosene until warmed up first on gasoline.
 Ditto for the semi-diesels such as the Farmall MD family.
