A while back, Luigi De Virgilio and I undertook to figure out how Lancia balanced their crankshafts for the V4 engines. It took a couple of years, and a lot of work, plus deep insights and guidance from John Cundy. Needless to say, it was written up, but...its not quite good enough. Probably have to finish this up (yes...). In the meantime, here's a teaser: part of the work included 3D models of all the V4 crankshafts. And once you have the model, why not make a print?
March 1 suggests spring is here. We know that it may snow tomorrow or that the weather is fickle, but for the day it was 55 degrees, and clear. So starts the ritual of getting the B20 up and running, after some months of slumber. Pull the air cleaner, prime the carburetors with electric pump, a bit of starter fluid, and it starts! I'm not sure why, but my B20 has a rough cold start, usually 3 cylinders or so for a few minutes. Maybe the compression is a bit high (9:1) or the early Weber single barrel carbs, and no choke. But start it did, and after about 10-15 minutes of warm up, off for the first drive of the season.
Normally a bit wary, as the car has been sitting, can be stiff, even a bit disappointing perhaps. But not this time: the B20 (as usual) read the mood, and decided to be absolutely flawless: brakes, suspension, engine, everything worked just as it should. No creaks, rattles, or anything off. Just a lovely 20 mile drive down the shores of Lake Michigan, amid traffic, but also some good speed work. What a great car - hard to imagine how it was at the time. Like a lovely violin - just on note. And a big thank you to the wizards of Turin.
