Installing a Muffl er (EVOM6 Inverted Wraparound Muffl er illustrated (not included))
The muffl er mounting accessory package
includes mounting screws (2), lock washers (2),
muffl er gaskets (2) and an L-wrench.
We suggest using high-temperature RTV
silicone as a locking agent on the muffl er screws
to keep them tight.
For reliable muffl er retention, 12mm of thread
engagement is recommended.
Connecting the Throttle Linkage
1. Use the provided ball-link to attach the throttle
linkage to the throttle arm on the carburetor.
2. Power ON the transmitter and receiver. Move
the throttle stick and throttle trim to center.
3. Place the servo arm on the throttle servo so
the arm is perpendicular (90°) to the throttle
linkage.
4. Ensure the throttle servo is moving in the
appropriate direction. The throttle servo arm
should move towards the engine when the
throttle stick is moved to high throttle. If it
doesn't, reverse the servo direction in your
transmitter. If you use servo reversing, you will
need to rebind your transmitter to the receiver
for failsafe to function properly.
5. Move the throttle stick to low throttle on the
transmitter. Reduce the throttle trim to its
lowest setting.
IMPORTANT: Tighten the muffl er screws after the
fi rst few tanks of fuel. The muffl er screws may
loosen from heat and vibration. After the third
tightening, no further muffl er loosening should
occur.
1. Put a lock washer on each of the muffl er
screws. Push the muffl er screws through the
muffl er.
2. Place the muffl er gasket over the muffl er
mounting screws.
3. Align the muffl er gasket with the exhaust
opening and the muffl er mounting screws.
4. Tighten the muffl er screws.
6. Move the linkage connected to the throttle
body to full-idle (away from engine). On
the servo arm, fi nd the hole that is closest to
16mm (5/8 in) from the center of the arm.
Mark the pushrod where it meets this hole.
7. Using pliers, bend the pushrod so there is a
90° bend at the mark.
8. Using a pushrod keeper, secure the pushrod
in the servo arm.
9. Check that the throttle arm on the carburetor
can travel fully open and fully closed (both
have hard stops). Adjust your transmitter
endpoints to ensure full travel.
10. If there is a large difference between the
endpoints, adjust the endpoints and sub-trim
to fi nd a balance where the endpoints are
approximately within 10% of each other.
