John o Neal: I think P. Reivers was kinda in a hurry and just gave you a quick answer that did have a lot of neat tricks. I do think Mr Reviers reply with the "gray matter" does not fit in good at all. I hope Pe R. Gives you more of a apology. We all must try and remember there are all types of people just learning kinda as you go. We do not all start out with high perform ace engines. Mainly we use what is available easy with not too much expense involved. Best Regards, Capt,n
