Recently picked up a '48 Ford 8N in Southern California (Orange County - used to work the orange groves near Disneyland) and moved it up to Northern California in the low Sierra Nevada mountains (3000 foot elevation). Tractor ran & I drove it onto the trailer in SoCal, but can't seem to get it started up here in the mountains. All I'm successful in doing is flooding the engine. I know that in flying carb equipped internal combustion engine airplanes we had to keep jockying with the fuel mixture (used similar carbs as on tractors) every time you climbed or descended in altitude. Other than "operator error" (which I've not ruled out, since its been over 15 years since I've been on any tractor, and over 50 years since I drove my grandfather's 8N), could the issue be that I need to adjust the carb for the altitude difference? Any thoughts, comments, suggestions, or jokes would be appreciated. Thanks!
