Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
hi Doug,I am wanting to blank the crank case breather off,because all it does is fill the air filter box with 2 stroke mixture.The pipe from the crank case has a one way valve and then is into the air box.I am sure earlier rotax engines used on SWM trials bikes ran fine without this system.Also I thought the oil in the fuel mixture was to lube the bottom end,so why would it be fed back into the carb inlet. Hope this helps, look forward to your reply.
Doug, thanks for that. I am confused, or may have missled you,but the bike is a 2 stroke and does not have oil in the crankcase it only has oil in the gearbox.The bike is 1985 model and runs a dellorto PHBS 26 carb.
