An E-Bay buy, the engine suffered tool drawer paint chipping in its previous life as an used engine. Now, the head is all red, with what else? Testors paint.

I prefixed this blog with [b]cool]/b], which I'm sure may bore some not into vintage engines and sound damping solutions.

I needed mufflers for the vintage McCoy and Enya engines. The following is how I solved the problem.

Photos 1 & 2: I had a spare YS muffler. I modified it to fit this Testors McCoy .40 Series 21 CL Black Head. I fitted it by filling the muffler mount holes, cutting a stainless steel hose clamp mounted with 4-40 screws drilled and tapping into the mount ends.

Photo 3: I mounted a Tatone EM-4 Calumet .09-.19 Muffler to an Enya .19-VI TV engine. Since I lacked prop washer and nut, I improvised. I drilled out a fender washer to fit the prop shaft. Nut is a spare from my parts bin.

Photo 4: The Enya ran hot. Photo shows the problem, an overly restrictive baffling system and too small an expansion chamber area.

Photo 5: I ground away as much baffling as practical. It still ran hot.

Photo 6: Solution resulted in converting this Calumet muffler to a Tongue muffler for a Testors McCoy .19 Red Head CL engine for a control line airplane.

Photo 7: On this venerable Enya .09-III TV, I ground the other EM-4 Calumet's mount lip to clear the cylinder. Because the .09 is left hand exhaust required the muffler to be mounted upside down. The baffling system is very restrictive, leading to what I am told many an engine ruin due to overheating, which my testing proved. Further modifications are pending.

Photo 8: Solution for the Enya .19-VI TV is the Tatone .29-.40 Peace Pipe Muffler. It ran cool and powerful with this muffler.
