I've been away from the forum for a while but I am glad to be back amongst friends. Some may recall my special air-cooled Norton Rotary. Well, I had all sorts of compression problems and finally gave in and stripped the engine down.
The long and the short of it was that the moly coating on both side plates had cracked and just came out with a finger nail. Lucky not to have had a complete engine catastrophe.
I refitted the engine but had all manner of problems setting up running and just left it for a couple of years because work got in the way. The one good thing about this current enforced lockdown is that I have had a chance to revisit it, and lo and behold, after refitting the carbs and air pipes it has started to behave nicely.
I've uploadede a short video file to youtube in case anyone is interested.
In the video it's running with a bit of choke so a bit fast but it idles at about 1,000rpm when warmed up.
Just need to wait until I can MOT it and take it out for a shake down.
Best wishes to all,
