Update, I really like free flowing air. 175 mains, 42 slows, 1 3/4 turns on the screws, leaned float by a mm, 87 octane, fp needle @ 2. Runs great from 800' to 12,000...prolly good under 800', didn't get that low yet. It roars, makes plenty more power.
I can up the mains from this easily, I was worried going to Colorado that it'd be too fat.
Rolled my own filter out of a scrap of 1/8" alloy and some buna grommets that hold it firm to the carb base. Bought the same itg filter as the cpr guys use...best $80 mod ever
