INtroductIoN
Thank you for buying an Evolution High-Performance Muffler. This muffler has been developed and tested for use with our small
case Evolution 60NX, 52NX and 46NX engines. This muffler will fit on other engines with the same mounting dimensions.
We’d like to hear your comments on the results you get from this Evolution Muffler.
INstallatIoN
The Evolution Muffler comes with two screws (these screws are available as replacement part EVOM101).
1. Remove the existing muffler and screws from the engine.
2. Apply sealant (hi-temp RTV) on the face of the muffler port. The face of the exhaust port may be rough, so a seal may be
needed. A paper gasket is not recommended, because paper tends to compress then loosen. Because of the nature of the
product, a small leak is acceptable.
3. Put the Evolution Muffler screws in the engine exhaust mounting holes and apply a small amount of thread sealant to the
screws. (We recommend PAAPT42 (blue) so you can remove the muffler when you want).
4. Tighten the screws into the Evolution Muffler using a T-handle instead of an L-handle wrench. Take care to tighten both
screws evenly to prevent distorting the engine case.
5. Connect the muffler pressure fitting to the fuel tank using medium-size silicone tubing. Make sure the tubing is not bent
and does not form a kink, so air flows freely. Connect the tank to the carburetor using the largest tubing that fits and seals.
Filters may be used, but only when clean with no leaks (we recommend the HAN143 Pro Fuel Filter).
6. Engine carburetor, low-speed and high-speed needles may need adjustment after installation of this muffler. Refer to your
engine manual for instructions.
Note: Due to increased rpm produced from the muffler, we recomend using the glow plug HAN3011.
