RE: best muffler for a super tiger .90
I run a MA 12 X 8 scimitar prop on mine ST G90, but while breakin in really rich she was taching at 12400 rpm, , I have run a few more tanks thru , but still not fully broken in, I plan to tach my engine today...if I can find those gaskets I bought for the muffler..mine vibrated off and burnt the gasket, ...just having trouble locating the packet of new ones I bought a few months back
I forgot to mention I run home brew and use only 5%... your specs dont sound right to me..but I'm no expert in these matters
