If carburated, the jets have to be changed for elevation....Did 4 jobs today at 6463'
I normally clean down here at 4800..
Each start took two attempts on the 370..
Normally it fires up which is one quick flip of the key...
Do carburetors get worn into a certain elevations and fight changes?
Carburetors don't change unless you change them. That's what makes them so great and not so great.
