Motor welded up... Almost...
How it all goes together. The bare chamber
1/2 The split throat outer on the chamber
Both halves of the split throat outer on the chamber.
End of the motor assembled (Rear outer not installed, its really just a sleeve.)
Detail showing the fit between the chamber outer and inner.
Detail of the end where passages end and go into the chamber above the cat pack
All welded up
Lastly doing the water flow showing no leaks on the bottom and all cooling channels are open and free.
I still have to work on the top end closure and top side catalyst retainer, but its really close and I’m happy with the results.
