My thanks to Jim Miller, my Onan was running rough etc. I followed your
advice and it turned out to be the points, I Burnished them and now it
runs fine EXCEPT it will sputter and die when I run both AC units. I
ran the unit for an hour and one AC for at least 20 minutes no problem,
but when the compressor for the other starts, the onan sputters and
starts to die, spraying start fluid in makes it worse and taking the air
cleaner loose makes it better. Also seems to run best with power needle
all the way in. It doesn't seem to be starving for fuel, actually the
opposite ? I rebuilt the carb (mistake) and probably messed something
up. Taking the carb apart again, what should I look for?
Thanks for any advice,
Ron Preston,

Take out the needle from the float bowl and check the o ring. If it bad and leaking replace it with an 1/4" od, 1/8" id.
When you said it runs best with the needle all the way in it's a clue that it's leaking.
