A while back I acquired a 1955 TO35 that had not been running for some time. Now that I have it running the engine makes a rapping sound at idle. Can't hear it at any other engine speed. As you gradually slow it down you don't hear anything until it gets right at idle. With hood and gas tank on it seemed to be coming from the left side of the engine about by #2 cylinder. Found a bent pushrod and replaced it. Still had the noise. Pulled the head and found one bad valve and the need for new guides. Had the head planed and installed new valves and guides. Still have the noise. This time we ran it without the hood or gas tank and determined that the noise is coming from the front by the governor. Then I remembered that last summer when I first got it running the governor seemed unresponsive. Could the governor be making this rapping sound?
I figured if anybody could help, you guys could. Thanks in advance.
