I'm thinking the engines vibration worked the bolts loose. I know people who build the Briggs & Stratton or Honda engines for Jr. Dragster or those race karts and they always have the crank shaft balanced. Also what RPM are you peaking at? Those engines stock are only designed for about 2000 rpm max. One of my customers son races Jr. Dragster. He started with a 5HP Briggs & Stratton. His redline I believe he told me is 5500 rpm. He has over $3000.00 in that engine and keeps a complete spare engine. He told me the only thing stock in the engine is the case. That really sucks that it come apart so quickly.I would talk to someone who builds this type of engine for as to why it come apart.
