Following a recent offer of a free Westwood Gemini, I've stripped it down to it's bare bones and managed to get it back to a reasonable condition.
I needed to purchase some new parts like ignition coil, HT lead and new NGK spark plug. Starter recoil assembly with rope and handle and new engine gaskets of course (in particular the correct thickness head gasket). The cylinder head was de-coked, cylinder bore de-glazed, inlet and exh valves lapped in and valve clearances adjusted to spec. Ignition timing reset by finding true TDC with a dial gauge and degree disc on the crankshaft. Zenith carb cleaned inside and out with carb cleaner and jets cleaned with compressed air. Similar for the fuel tank with a new fuel pipe fitted. The 'gloop' in the chaincase was removed as far as possible and refilled with new oil. Unfortunately, the chaincase is sealed for life though I would have liked to get inside and give it a proper clean and renew the axle shaft seals. Everything torque tightened where I could find the figures and finally primed and painted in rattle can engine enamel. Stickers from Titch at Machinery Decals, which are great. It started 2nd pull and the carb adjusted once warmed-up. Looking forward to using it when I get my allotment. Photos below...
Here's the completed machine...
