Saving Old Seagulls

Ok, so pulled the whole top end to bits again, connecting rod was bent but luckily had another one in my box of spares. Checked the fit on the crack case while it was apart and it was like a sieve. Got a tile and taped some 320 grit to it and flattened both halfs with a figure 8 motion. Put it toget...

I will check the crankcase fit when it's apart. I don't have any engineers blue so I'll have a go with a sooty flame to blacken the surface. Not tried it before but it's how seals on shotguns are checked so should work fine and will save me from buying the blue.

There was a washer under the locking screw on the points so as it was tightened it would lift the dowel under the pivot pin and allow the points to move out of adjustment as the flywheel spun. I removed the washer, adjusted the points and tig...

After a complete strip down, clean and polish I have the first motor back together again with new gaskets, plug etc. Initially it had a leaky float needle seat, ...
