Hey guys I need a little help with jetting my carb. I was at camperjam this past week and my van ran way better up in the mountains. I am running a Weber progressive on a 2L pancake engine. So my question is what jets should I change, the main air, the main fuel or the idle jet. I'm guessing the thinner air would mean I need to enlarge my main air jet but I really don't know for sure. Any input would be appreciated. Thx.
