I have to take the motor

[rkuik]

please dont just shoot me, but am seeing a lot about a knock in the old single Kohlers. do you really have an issue or is it just the Kohler knock? an old warranty rep years ago said to widen the gap on the plug, if it starts going away, you can either leave it there or bring it back. if you have the widen gap, you will loose some power. just a thought.

I have not heard about the plug gap but have heard to lessen the point gap.

My experience with the so-called Kohler knock, was to either adjust the points gap (don't remember if larger or smaller gap) or the knock came from the front pto when it was not in use. The fix was to put the dumb little springs in (that never stayed in for me) or the best fix I discovered was to fill in the gaps between the clutch plate and clutch basket with automotive urethane windshield glue.

I had a rebuilt motor knock after some use
Turned out the front bearing was bad
It looked and turned free
I put a different one in and that fixed it

Seems like it’s a common problem and like with my neighbor with the 149 he can’t hear it like i can.
