Rusty,
The side housings were lapped and were within specs.  I tried to get the=
 oil
springs installed correctly but at this point I'm double guessing=
 everything.
I will check the oil vent line for mist and run a pressure check on the=
 coolant.
Anyone have a cheap way do that--local Auto Zone, etc stores don't have a 
pressure tester to rent.  I am going to run a compression test just to get 
some numbers but I'm getting good chugs when rotated.  I premixed and am
running the oil metering pump but I haven't seen oil in the lines.  I plan=
 to investigate
that later.  I  put about four ounces in four gallons of gas and have the=
 metering pump 
if it is working.  Thanks for the suggestions.    

Jim


=A0=A0Hi Jim, =A0=A0What shape were the side housings in?=A0
>=A0Were they smooth, flat, and all within specs?=A0=A0Were there any dark
>=A0spots near the center hole of the housings?=A0=A0=A0=A0I can't recall who
>=A0asked it, but making sure you put the oil springs in the proper
>=A0direction is a good point.=A0=A0If those were allowed to spin, I bet
>=A0the oil control o-rings wouldn't last long.=A0=A0=A0=A0Here's something
>=A0else to look for.=A0=A0Check your oil vent line when you're running.=A0
>=A0Is there oil mist blowing out?=A0=A0If so, you're not only burning oil,
>=A0but losing compression past the seals at the same time.=A0=A0This would
>=A0be a bad sign.=A0=A0Ask me how I know this :-) =A0=A0If you're worried
>=A0about the=A0coolant seals, there are some pressure tests you could do
>=A0for that as well.=A0=A0=A0=A0=A0Are you running the oil metering pump, or pre-
>=A0mix?=A0=A0Is there any chance you have=A0way too much oil with either?=A0=A0=A0=A0
>=A0 Good luck, Rusty (single rotor mount almost complete) =A0=A0
