MTD YM the only way it starts is to plug the crankshaft breather tube
I just bought a 1998 MTD Yard Machines Lawn tractor with a 20 hp B&S engine. I found the only way to start it is to plug the crankshaft breather tube. as soon as I take my finger off (and it sprays oil everywhere) it shuts off. Not sure where to start trouble shooting. Maybe the breather tube is installed wrong?
