Hard starting or a gradual loss of perfor-
mance can be caused by carbon deposits
lodged in the muffler's spark arrester
screen. For maximum performance, the
arrester screen should be periodically
removed and cleaned with a small wire
brush.
 The muffler used on Model 85s has
an internal baffle that can be re-
moved for cleaning by removing the
two nuts on the muffler cover.
