As Martin P can testify, the latest Onan looks quite twee with its maroon paintwork and lining, too bad it was left outside with the plugs out!
It's an April 1944 model, same as our red one, and came at a fairly decent price.
One piston is severely stuck (rainwater in the bore) and the other is nearly free, both were within 1/4" of the top of the bore. It's been soaking in WD-40 for three days.
We blagged an offcut of 3" Nylon this afternoon, and turned it down to closely fit the bores. Application of a BIG nylon faced mallet brought some movement downwards, so we filled the bore up with WD-40 again and left it.
The pistons are aluminium so we don't want to crack them by applying too much force. Once we have the piston low enough, we can clean the bore above it and move it up to the top of the bore.
Magneto is missing, lots of bodgy bits here and there, but generally it is all nuts and bolts stuff: car wheelnuts used as spacers, that sort of thing!
