This is the engine as it was received from my good friend Richard Mcfadden.

Very sad state indeed, so lets start with a jolly good clean and start making a replacement crankshaft and go from there..............

Here is the finished crank.

And  here's the bottom end all assembled and ready to go.

Next it's onto the cylinder liner reworking.......

Re lapped the liner and made and fitted an new piston and contra piston, gudgeon pin and con-rod. Then reassembled and ready to run.
