Sold out Cox .049 silencers for sale
These silencers are similar in design to the Cox .020 mufflers but slightly larger to accommodate the Cox .049 engine
Top of silencer
Bottom of silencer
Installation instructions
Please check the cylinder dimensions:
As the cylinder sleeve sizes vary slightly you might have to adjust the fit?
The parts that interfere (i.D.) with the engine cylinder will need to be shaped. (enlarged?)
Using a slightly undersized wooden dowel and some 220-grit sandpaper wrapped around the dowel to carefully enlarger the hole for the cylinder sleeve by twisting the dowel/sandpaper in the hole to enlarge it. Don't overdo it now! you want a snug /slip fit.
Included with the silencer are two different thickness size shims (.008" / .012") (0.2mm/ 0.3mm) to give the silencer a tight enough fit when the cylinder is tightened down and the silencer is snug enough to not move. If it does, you'll need to add one of the shims on the bottom side of the silencer.
One more FYI (if necessary) -- use a small amount of Permatex (non-hardening) gasket sealant on the upper and lower faces of the silencer to get a really good seal.
The exhaust tubing is 5mm I.D. diameter.
Thanks,

I bought 1 to test, the 5mm ID header should help the engine breath.
Thank you Mike!
