On on my pressure fed engine in the Arrow, the spring loaded shaft that the starter handle engages has a brass bush that both retains the spring and bears against the nose cone aluminium end. The bush is crudely made, so is possibly not original, and has been slowly grinding away the aluminium!
Im making a new one, but before I start could anyone tell me...
is the original design bush brass, bronze or steel and does it bear on the nose cone directly or should there be sleeve. Also the bush has three curious grooves on its inside diameter, I cant see the purpose of these grooves - can anyone with a speedy engine remember seeing these on their engine.
A picture of an original bush would be greatly appreciated, even the view with just the chrome nut removed would be useful
Finally I thought there was a parts list book that had a section view of the speedy engine, I cant find it on the archive. Thoughts as to where I may have seen this?
