The usual very well done and informative video from Tubs… thank you.
Just to elaborate on the last issue “too warn to fix” …. yes that can happen with these real small motors. In many cases that issue is low or no crankcase compression due to worn crankshaft bushings. Since there are no crankcase seals, crankcase sealing depends on the tightness of the crankshaft bushings. Low crankcase compression will cause hard or no starting and poor low speed running. Check for excessive back and forth movement of the flywheel, indicating worn bushings. A richer mix of heavy 40 W oil may help.
Can this problem be fixed? yes, if you have a machine shop or a friendly neighborhood machinist.
