Good Morning to you all:
A week or so ago, I wrote about the sudden stoppage of our little C and the subsequent "stuck" motor and ask for help. I appreciate all the responses. And I have good news: Saturday I finally had a chance to get back to the little C for a look-see (I currently commute from Houston to our home in Southwest Michigan; don't ask, long story, but hopefully it won't be that way much longer!!) and I took apart the governor as some of you suggested to check the flyweights. They were both there, but the whole assembly was really worn and will be replaced, and the motor was still "stuck".
I stood back a few minutes and review all that had happened up to the point of the motor seizing, and I began to suspect the starter.
Sure enough, when I pulled the starter, it was still engaged to the ring gear. Pulling it out freed the engine and the sun popped out from behind a very dark cloud! Thinking back over the last several times I had started the little C, there was a lot of hesitation from the starter, and I surmise that the "last time", the drive simply stayed engaged to the flywheel and the engine drove the starter till it overheated, seized, and locked up the motor. Fortunately, it appears that no damage was done to the ring gear, and the fix will be replacement of the starter. A much easier fix than having to split the tractor.
Now, my questions. In reinstalling the new governor, I will have to reset the distributor. I understand how timing works and will get #1 cylinder on TDC ready to fire. The service manual says to look for the "FIRE" timing mark on the left-hand side of the torque tube. I looked all over the left-hand side and I don't see what the manual is refering to. I don't see a plug or mark or anything.
Do any of you know what this is about? Is the distributor timed to fire AT TDC or is there a certain number of degrees BEFORE TDC where the distributor has to be set?
And one final question. Looking close at the carburetor (it's a Zenith), I noticed a broken spring on the back side of the carburetor.
Should there be a spring on the throttle shaft? If so, where would it attach to the block? Is this to aid in the operation of the governor, or has someone tried to compensate for the worn governor by installing a spring that otherwise wouldn't be there?
Thanks for all your help. Really enjoy reading the comments from y'all.
