Good demonstration Thanks, you cannot buy quality like these Military Generators now, would cost Thousands £ to make. The governor - tick over setting on mine had to be altered gradually with small adjustments, but works great now increases speed under load, was a bit unstable-fast initially caused by over rich mixture & slightly retarded timing.

These little Onan's seem to be coming out of the woodwork !! I have one in the UK and until the advent of the internet and youtube was struggling to find any info ! Now there are 3 including yours on youtube ! I have a copy of the manual if you need it ? Smokstak is a really good resource.

Many thanks for the offer of a manual, I'd certainly take you up on the offer but I have found a manual on a UK internet site,

I lived in the UK (Denham ne Heathrow) until 1999. Does the voltage vary on yours as much as mine does ?

[byrnestuff]

Yep, thanks for the comment, I know the voltage/rpm could be made to regulate better when load is applied....and I would prefer that it did ! ....but there is no adjuster on this genset that will do this that i know of......when I get time I need to experiment with different governer springs and/or change the throttle linkage....to try to get an improvement

Try adjusting for a bit less speed droop (slowing down) when under load. The Voltage drops more than it should going from no load to 1000 Watts. It will do better at 2000 and 3000 Watts too.
