Racer X#99 and Alan,
Thanks for your feedback. It's a relef to know that something that I stumbled into doing has a solid, technical experience basis to it. Your experience, both personal and observed, is much appreciated.

I forgot to mention that I have the Accusump wired both into the ignition and into a separate switch that allows me to rev the engine to increase oil pressure, then to close the valve before letting the rev's drop off. This process stores oil at a higher pressure for faster oiling at startup.
If you fellows have any other suggestions for using the pre-oiler, I'd welcome it.

All the best,
Randy Klein
