When I hooked up the new engine (same carb, same throttle cable) I immediately noticed that I had very little "throw" in the throttle. Where before, I could move the throttle control from stop to stop, now I only have about 1/2" to 3/4" of usable movement.
Also, right now, the response to a cable movement at the throttle on the carb is not what it should be. When I manually adjust the carb throttle, I get a nice, smooth adjustment of power, however when I use the throttle control via the cable, I basically have idle or wide open.
I made the "Initial Adjustment" as stated in the Service Manual, and have made the "Speed Adjustment" to set the max RPMs, and things are somewhat better, but it's still clearly not right.
My main question is this:
I have reviewed the instructions in the Service Manual, and am confused by one of the steps. Step 4 in section 6.27 (Throttle Wire Installation) tells me to remove the Drive Pin from the Speed Control Disc. I see no instructions indicating that it should be replaced. My problem is that every tractor that I've checked around here still has the Pin. What am I missing? I'm afraid that I'll maul it up removing it, then find I need to put it back. Am I safe to remove the pin and not put it back?
As always, thanks for any help, suggestions or personal experience!
Here's what the Manual says:
