I have less than 1 hour on my new 106 motor. I went out to start it and it had no compression. I pulled the head off and from what it looks like the intake vavle floated open and then the exhaust bent when it smacked into it. I have put new valves in it and it seems to run fine but I am wondering what caused the intake to float and will it do it again? 2 of my friends have the same motor set up and they run the s*** out of them with no problems. Is there something else I should be checking?
