Hi micka,
please post a picture of the governor linkage and spring. It sounds as if there is an assembly error. No big deal to put right unless you allow it to over-rev before you fix the governor problem.

hi grumpy this is what I have, if they turn out

Thanks micka, Here is the Illustrated Parts List for your 11 hp engine:

Here is the diagram showing how your links should be set up:


Your engine is shown in Fig. 106. Your links seem correct to me.

You haven't said that you set up the rack and pinion governor control correctly. Here is the Operator's Manual:

Refer to Page 7 of the Operator's Manual. Here is what it tells you to do to adjust the setup so the governor can work correctly:

will try thanks grumpy

hi grumpy I done the adjustments, also I think because I was using the governor spring of the old 12.5hp I used the governor arm off the 12.5, everything looked a lot better and worked, there was a difference in the two arms

Usually you can tell whether the tension on the governor spring is about right, micka, but not until you've been through all this a few times. I'm glad you've got it running properly, and haven't broken anything or wasted a lot of money along the way.

I'll close this thread.
