Andrew,
What carb' needles are you using? In my experience in the mountains of
Colorado, "spitting" is caused by too lean a mixture. One has to have a
weaker needle at this altitude but in the Winter when the air is denser and
therefore has more oxygen per cube the fuel/oxygen ratio that was correct in
Summer is now all wrong! Try lowering the jet a couple of flats and see if
that helps. If it does, then you need a richer needle.
Cheers, "Bob".
