I have for sale "Five" Cox .049 silencers with gasket/shims.
They are designed similar to the Cox car silencer where the cylinder screws down onto the silencer and tightens down on the crankcase.

These silencers are similar in design to the Cox .020 mufflers but slightly larger to accommodate the Cox .049 engine

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.

If you are still interested in one of them let me know.
