Using a Phillips or slotted screwdriver - turn screw 1/4
to 1/2  turn clockwise  (to the  right). Unit  should then
idle properly. (Figure 5-2H)
Never use straight gasoline in your unit.This will cause
permanent engine  damage and  void the manufactur-
er’s warranty for that product. Never use a fuel mixture that
has been stored for over 90  days.
If  2-cycle  lubricant   other  than  Genuine  McCulloch
Lubricant is to be used, it must be a premium grade oil
for 2-cycle air cooled engines mixed at  a 40:1 ratio. Do not
use  any 2-cycle  oil product  with  a recommended  mixing
ratio  of  100:1.  If  insufficient  lubrication  is  the  cause  of
engine damage, it voids the manufacturer’s engine warran-
ty for that occurrence.

MIXING FUEL
Some conventional gasolines  are being blended  with oxy-
genates  such as  alcohol or  an  ether compound  to  meet
clean air standards. Your McCulloch engine  is designed to
operate  on   any  gasoline   intended  for  automotive   use
including oxygenated gasolines.
Mix fuel  with  Genuine McCulloch  brand 2  cycle oil  in an
approved container. Use mixing table for correct ratio of fuel
to oil. Shake container to ensure thorough mix.
Lack of lubrication voids engine warranty.

mation on the bar and chain.
