its an early 70's motor. what are the carb and choke settings? thanks

[Krom]

if it has remote adjusters for low and high speed mixture, start at 1.5 turns out on low, and .75 on high, tune from there.

AFIK there is no adjustment or setting for the choke

whats the white plastic "dial" at the top of the carb?
