[AT] Jim Dandy Question

[Larry Goss]

BTW, Someone on this thread mentioned they were working with a Command engine -- 18 or 20 horse.  Be aware that the carburetor on that engine has a tendency to gum up, refuses to idle, finally gets to the point it will not run, etc.  It's all caused by a kind of algae growth in the anti-Dieseling valve on the carburetor.  The valve is held to the outside of the carburetor with a couple of Phillips head screws.  Carefully take it off, clean the gum out of the plastic parts, and it will run like new again.  The growth is time dependent.  It appears to only be a problem in Command engines that set for long periods.
