You mean the answers to all the world's problems can't be found on RCU? [sm=eek.gif] If there is one thing I know for sure, it's that I don't know everything for sure! There is always more to learn about anything. Other peoples experiences can be very useful tools, it's how you use them that makes a difference. There are many that have a much broader knowledge about what we are all doing here, but for whatever reason gas engines do seem to like my touch.
