    yeah, i was euphoric. ill start using 20:1 maybe? i have a #63 jet in since that seems to work alright, and my #70 didn't really work too well when i first had it in, even with the muffler backed out. i feel like ive found the right jet, too.

    I believe that as long as you are using a good synthetic or semi-synthetic 2 stroke oil you can go 24 to 1 for break in and 32 to 1 after but I know there are lots of opinions on this.

    128 oz in a gallon
    24 to 1 = 128/24 = 5.33 oz
    32 to 1 = 128/32 = 4.00 oz
