A quick laugh: There is no such thing as a Cummings engine!
If you're really bored, do a search on the cumminsforum for the word "Cummings". I just saw a post with Cummings in the sig and that prompted my interest. Reminded me of a truck I saw in Moab one time with this huge mud flap extending completely across the bottom of the truck and C U M M I N G S stenciled in white across the mudflup (wish I had a camera).
Maybe it should be stickied somewhere for newbies that there is no such thing as a Cummings.
