If I read right you are at a 117 so we are running a bit different..lol im also in Colorado and that may affect yours compared to mine jetting wise.
I changed my idle jet from the stock 22.5 and im running a 13 tooth gear. Just a bit different than what you got going. Play with you jetting, buy a 10 pack of a range and mess around. The VM20 is so easy to change them out...i love it
