1864 Exhaust
 

Recently got a 1864 with the CH 18S motor. Previous owner had a overheat problem and dropped a valve. He fixed it, but still ran hot. Bought some parts from the Cubmaster in VT. He asked about the muffler. If it sounded like a jar of pennies? It did. He stated it was most likely the problem (plugging exhaust opening) and to get a new one. Has anyone opened the exhaust up and removed the baffles? Going to try it? How does it run after if you have done this? I know its going to be loud.



the SN to my machine is 868,3XX

I've never done what you suggest, but at this point you don't have much to lose. If it doesn't work you can buy a new muffler. Last time I checked they were still available.

I would check that the cooling fins are clean and that it's not running lean. That could also make it run hot.

I have several times. It is a broken baffle. Cut open the right side and weld it up then weld a cap on the opening. Will be a little louder when done!

If this goes bad for you the muffler is still available but it is pricy.
