However, during road testing. Magneto quit unexpectedly and discovered magneto brass screw failures resulting in two plates floating around. Thank goodness caught problem before any damage was done. Of course, had to pull motor due to fix magneto. During inspection of transmission, gearing and other transmission parts, (bushings, clutch plates, drums etc) were in amazing condition.
Inspecting motor for due diligence while it is out. Motor extremely clean inside. Some carbon in the sump, but no metal bits in pan, Crankshaft looks great. No noticeable bearing run out, axial end play only .005". Con rods, pistons look good. cylinder walls very good. The only issue seen was pitting of the cams shaft. Worst was intake and exhaust on #3 but #4 as well, Number 1 & 2 also have some pitting but much less. See photos: If this was a daily driver, I know the answer as to how much pitting is too much. But car will be parade car with only limited driving < 100 / year. Is this amount of pitting worth pulling / replacing cam / lifters etc. or should I take "it ain't broke, so don't fix it" approach". I am on the fence. Looking for second, (3rd,4th...347th) opinion
