Ronnie, Thanks for the response. I have the manual and I believe sect 5, sheet 3.00 applies to a left drive 3100. The page you referenced is for right hand drive with a hand-brake. However, I agree with you that the spring should have only enough tension (when released) to keep the parts from rattling around. I’ll drill a hole for the extender that gets me there. Have a good holiday weekend.
