Kohler Genset Fan Question

Scott,

Interesting comment you posted, based on my recent experience:

The Perkins on my 83 PT40 also runs consistently at 160 and used to
smoke continuously, like yours is doing. I just changed the Perkins
"lift pump" (aka fuel pump in the U.S.) and sealed up some fuel line
air leaks in the process of doing so. It just dawned on me over this
past weekend while I was running the genset that there was no smoke,
less odor, and the Perkins seemed to be running smoother than ever
before. I am left to wonder if the smoke problem was *more* due to a
fuel mixture problem all along, thanks to the developing air leaks?
The Perkins always took two tries to get it started and now it starts
immediately, so I guess I have had the minor air leaks for some time....

My 2 cents since you asked for tips.
