I tell guys a lot of things basically everyday. But only 50% of them actual listen to me. Some love to try things on there own. Then when bad things happen, then they do it correctly.
But with the money in the parts they just lost. They could have bought the right stuff in the beginning.
I have a friend running one of those 1.5 lb vertical flywheels on his modified 5hp briggs. I told him not to do it, but he did anyway. But it did run good, until it blew up last weekend. But the flywheel was still good????
