... First off I don't really think that running your engine at wide open throttle in neutral is a very good idea..

Ed,
Thanks for posting that. You may have just saved or at least extended the lifetimes of a few engines.

I have an additional question that I will post as a new thread. Please chime in if you have an opinion.

Fair Winds,

Rick

BTW guys... it was read by an optical tach check so we do know that the 4K is an accurate number. Good to know it it probably just a governor adjustment.

Rick, if you follow quantum and string theory and all the wierd science that suggests there are 11 dimensions and now *confirms* there are five states of matter, including one that can radically slow down the speed of light...

Hey, it could happen.<G>

I suspect that physics as we "know" it may soon be remembered with the same laughter as "everything is made of earth, wind, water, and fire" and there is a mysterious aether permeating the universe. Well...the aether may actually be true, the stuff they are suggesting about dark matter and dark energy fits the bill closely enough.<G>

Cam,
Thanks for that info. It's an involved and technical proceedure to set the adjustment of the Fuel Injection Pump and Govener; way to much for this discussion, and quite possibly not even necessary as the injection pump appears to be operating without complaint. The motor appears to be operating ok, there are no reports of any other issues except high rpm's in neutral, which is what the manual calls for; verification at no load test. Why not break the wire on the Maximum speed adjustment bolt to lower the no load RPM's to 3600. Then rewire the maximum speed adjustment bolt. The wire I would asume is an antitampering concept. Another alterenative as Ed pointed out in an earlier post is to not run the engine at full throttle, which imho is as easy as it can get to solve this issue.
