5.1.1 Remove the muffler, prop nut and prop washer
from your engine.
Engines vary quite a bit in sizes, styles and brands but
most have mounting lugs, a carburettor with a throttle
(speed) control arm, a prop washer, a prop nut and a
muffler. The procedure we describe here assumes that
you are mounting a 2-stroke engine that has a side
exhaust on the right (when viewed from behind looking
forward) and a throttle control arm on the right.
