Ed,
I can syphathise with you. I didn't make it this year
either.  I was supose to fly down with another builder
on Saturday, but no luck.  The weather in SC has been
the same crap that you have had.  

Some good news today.  I flew the Cozy this morning
(finally), and got a look at the temperatures with the
new scoops.  I need to add a couple of bolts to hold
the oil plenum to the cowling, but even with it
blowing by allot of air, the temperatures were better
than they had ever been.  The bad news is that my oil
leak is back on the redrive.  It had stopped for a
while, and I had attributed it to restriction in the
drain line, but today it started leaking again.  Looks
like I'm going to have to replace it.
