Years ago I converted an 8 horse
air cooled Kohler engine to a water cooled engine. It ran much quieter.
The water jacket provides considerable damping.

I'm curious how you did this. Weld up a water jacket around the cylinder?

Lane


No. The cylinder was mounted on a rotary table so the fins could be either
reduced or eliminated, using a stub arbor and a side cutter, then a
stainless band was fabricated that was held by a pair of stainless hose
clamps. The top and bottom fins were left almost full size in order to
create the water area between them. The fins didn't go all around, so the
jacket terminated with pressure pads. It worked like a charm. Made a new
head from aluminum, and a water pump. This went into a boat that didn't
have room for a commercial power plant. It drove an 80 amp alternator and
worked flawlessly as long as we had the boat, which had an electric
refrigerator, the reason for the needed additional charging capacity. I
have pics if you're interested. Let me know and I'll forward them to you.

I wouldn't mind seeing a picture or two of that Harold.

The the OP, I got a box of earplugs and I dig a pair out when it's time
to run the lawn equipment.

It might be that you've got too big of a muffler on it- can't get enough
backpressure to really break up the impulses..
