YS 63 Muffler
Well I have the copper RTV silicon already, and I have the parts that are left over from my broken O.S. 70. I was digging around in one of my misc,\junk boxs and found some lock washers that fit the pipe so I am going to use RTV and the washers.
What prop and fuel are you using??? Just wondering so I can compare itto mine with a 13X6 running on YS 20\20 fuel by Performance Plus.
