I have an 18hp Vanguard that was on an air compressor. I need to set the governor for my application, a 6 wheel amphibious vehicle. Is 3600 RPM the recommended upper RPM for this type of engine?

IIRC 3400 +-200 according to the manual..
so yes 3600 is the recommended maximum
if I'm not mistaking that is...
Oh wait.. OHV or older L-head? (which I think was 3300 *headscratch* I can't remember)

Soo good news and bad news...
the service manual I have does NOT give a definite answer to your question..
it only refers to the NO-LOAD rpm to be taken from another manual
the single time it lists NO LOAD rpms is for fixed speed generators
(3krpm-50cycle 3150rpm, 3.6krpm-60cycle 3750rpm , both regulated)
BUT all testing on the alternator (and most testing of the oil pressure) is done at 3600 as far as I can see ...
So yeah 3600 is still the value I'd go by.

ps:

Thanks Sid. The RPM's are low right now. Doesn't want to open the driver (Comet 94c) all the way. A few more RPM's should do it.
