Onan propane generator operation at high altitude

"As with any other gas appliance it is starving for air."

Not the only thing starving for air. Last time we drove here gradually rising in altitude over several weeks but this time it was 1 hour from sea level to high altitude. Gasp.

Yes, figured it was just a mixture problem so will see how it goes once we get down a bit and then start worrying if it still doesn't start.



Not sure what sort of carburation it has - but given the LP on the model number, I assume it was done at factory.
