Have the thin KN filter oil for now, will try thicker stuff if that fails. Lots of purpose made foam filter oil choices, might be able to get some locally. If that fails, tacky bar oil is worth a try, always some of that around.
Mods on the saw so far are to the muffler and just port matching the intake. AM cylinder is stock, but I was thinking of raising the exhaust port a bit and dropping the intake, and maybe a bigger carb, the stock one is quite small. Still, power is pretty respectable for it's displacement, and it's picking up revs as it breaks in.
Wonder if the vibration issue is from those massive pork chops on the crankshaft, and if drilling them would balance the assembly better. The crankshaft from a 141 looks identical with the exception of smaller counter weights, maybe that one would fit.
This is an early version, non strato. Had a stock strato pp 4218a, the wild thing would put it to shame power wise, the muffler mod no doubt makes a big difference.
