RE: What does it mean when...???
What are your runing temps at?????? Sounds like you are getting to hot and causing vapor lock or boil over, you might what to richen up the mixture and see if that brings you temps down. You want them aroung 220 to 260 over that I would say you are way to hot. So try first to run it around and get it going good and thne take a temp reading and go from there. I would think from what you are saying you will be riching up the mixture to cool her down.
