1. Attached is a photo of Acme AT 330 12 hp engine governor to carburetor link on a BCS 605 tractor.
a. I purchased the 605 this summer [it was not running]
b. Cannot get the engine to idle at a reasonable RPM [I do not have a tachometer]. Engine should idle at 1100 RPM [see Large Air-Cooled Engines, 1988 and prior, Service Manual, 4th edition, page 39]
c. The governor to carburetor link is threaded through the spring. [see attached photo]. That is the way it was when I bought it. Is that the correct assembly? I assume the spring's purpose is to hold the link in place. Is that correct? I also assume that this small spring does not have an effect on idle speed. The spring does not seem to be causing the link to hold the throttle open.
d. I have adjusted the lever located below the carburetor that attaches to the throttle cable. It moves freely.
e. The coil spring that connects the lever to the base of the governor lever is in place.
f. The spring that pushes the lever back to the idle position is in place and seems to be strong.
g. If I push the governor lever in a direction away from the carburetor the throttle stop screw will touch the carburetor body and the engine will attain a much slower RPM that may be close to 1100 RPM.
h. Do you have suggestions for adjusting this linkage?
