I have a carberated Lycoming O-320.  I'm installing the primer lines and I
need to know the following:

       o How do you flair the 1/8" copper tubing for the AN fittings.  My
flairing tools works down to 1/4 tube only?  Is an automotive 45 degree
flairing tool sufficient?

       o What type of solder flux should be used to attach the nipples
onto the end of each of the primer lines that fasten to the engine inlet
ports?  Is resin core solder, used for copper pipe plumbing sufficient?
