The engine model is CH 3007D068162 Ser # 3007D003. It keeps blowing off radiator hoses and even poped the top off the radiator. Engine runs really well though. Pressure tested radiator and it holds, weird. Any suggestions.
Have you tested the rad cap to ensure it'll release pressure ? That's where I would start.
First off, welcome to the forum!
Not sure on your issue, but it sounds like a head gasket (or worse ) so that compression from the cylinders is getting into your cooling system. I've had a couple engines with such issues. They both ran fine (other than desire to overheat as they blew up cooling system parts).
Check and see if there is bubbles in the radiator coolant when engine is warm, If so that means head gasket like Kiwi06 stated.
