John asks- >Can anyone please tell me where the primer lines should enter the engine?
If you're talking about the Corvair engine, he obvious place is at the base of the carb mounting pad, where there is already a hole and where fuel can go right into the log. There are small tubes sticking out but you pull those and tap the hole to receive the primer fittings. You can see pictures of this on William Wynne's Pietenpol setup, starboard and port, at http://www.flysquirrel.net/piets/WWVair05.jpg and WWVair07.jpg >Also what size hole and thread size should be used? I believe I tapped the hole for 1/8" NPT for the brass fitting shown, and I believe I got the primer fittings from Aircraft Spruce, info on the bits and pieces at http://www.aircraftspruce.com/catalog/hapages/primerfittings.php If you're talking about something other than the Corvair, I can't help you!
