YS 20 SR 2 storke (120 CI)
I obtained an older YS 2 stroke (120 ci). It hand cranks eiasly on the beanch and runs great for about two minutes then quits. I don't know how to try adjusting the regulator. Also I can not find any information about this engine. If anyone has an instruction manual or a muffler for this, please advise.
