I just brought a JLG 40HA, Ford 4 cylinder, dual-fuel man lift from Oklahoma (2,000 ft) to Montana (6,000 ft). It ran fine on propane in OK, but won't stay running under load in MT. There is a 4,000 foot elevation difference between the two states. How do I adjust the propane fuel system to accommodate this elevation (thinner air) difference? I am guessing that this is the issue based on the circumstances of the elevation change. It could be something else.
