carbs and elevation (1 Viewer)

[snailwagon]

I have an old single barrel d40 carb and I' m curious if these guys run into performance problems above 10,000' elevation. Like, do they even run. IF so, whatcha do to make em' work better, lower the float a bunch? No lean metering rod in this model.

theere is a lean /econ metering rod some can with it stached in the middle of the card in a holder. I run the lean rod all the time because most of the wheeling around hear is above 4000 ft and up to 9500 now and then. The carb will do fine if im not running down the freeway at elevations i bump the timing about 1/2 turn on the dizzy to help it start and pull better out of the hole
