But I wanted a Blue Head (had one in a Kiel Kraft Spectre in 1959/60, I think), so the head got skimmed and re-anodized. The crankcase got panel beaten by turning an undersize screw-in plug, gently bashing away with a little brass hammer until it looked round, then unscrewing the mandrel to "restore" the thread. Must have worked as the backplate screwed right in and does not leak! Another needle valve assembly was made along with a new drive washer, which was pressed back onto the cranshaft spline (who ever heard of a screw-on drive washer?).
The case had the ultra-sonic cleaning job done and with everything re-assembled, it certainly looked ok-ish. This engine is the mate to my other Taipan 1.5 cc and for all the butchery the engine has suffered, the piston and liner look ok, so given a con-rod, it should run.
At the time this page was first written, I'd decided that if I could not get the actual rod length, I'll make an educated guess Real Soon Now. Before that happened, I lucked on to a complete engine, with only a few multi-grip marks in the cooling head. This gave the dimensions for the conrod, and for the split thimble NVA. The CAD drawing of the latter is presented here in reduced size, but it may help other Taipan restorers.
