A buddy and mine picked this up at the local scrap metal heap at the tip.
After dismantling and inspection, I decided it was in surprisingly good order inside, despite the rough exterior condition.
I have cut it down in the usual way, increased the compression ratio and adjust the port timing to suit.
I made a spark plug adapter to fit a CM-6 plug, as the 14 mm plug that it came with stuck out to far near the propeller when the lead was fitted.
Running on AvGas and Stihl Ultra oil @ 30:1.

First run today, after some starting problems. Some tuning and fiddling required, but it goes ok.
17 x 6 propeller.
