gary, you might want to start a new thread. Your problem will most likely get lost in this thread.
There should be no correlation between the 2. If the head gasket were the problem it would not run very well if at all. If you pull the crank drain plugs and see coolant then you know you have a problem there. I would start with making sure the carbs are completely clean and properly adjusted.
