Re: A22 Muffler

Hi Gord,

My memory is getting pretty bad lately and its been some time since dealing with my original type muffler...I do recall replacing the inner pipe and remember drilling a lot of holes that were larger then original, I can't recall capping off that inner pipe or if it is even suppost to be capped off, I wanted as little back pressure as possiable....One other thing I did was to open up that exhaust exit slot in the bottom back of the backbone tube/muffler housing, to me It seamed that that was a sizable restriction.
My A-22 has always ran or sound like it has an exhaust restriction or ign timing that you can't quite get dialed in just right....However for some reason on a cool damp morning that all goes away and she runs pretty strong?
