    What's the size of the stud on the gas tank that comes with the 2 stroke engine kits?

    seen 2 diff sizes, there may be more - tuck it under your arm when going to h/w store to look for some

    I got the smaller 2L tank if that helps.

    then I'd guess 5x1.0, but the chinese tend to use whatever is handy

    The 2L tanks use 5 mm studs.

    The larger tanks use 6 mm 1.0 which is the same size as most of the fasteners on the motors.

    standard tanks, M5 x 0.8

    larger tanks, M6 x 1.0

    the chinese may be lax, but they do tend to use ISO standard threads still.

    if only i had realised lifan uses M7 studs rather than hondas M8 studs back when i was rebuilding a certain engine... oops :)
