Hi, Mark....yes, the brochure arrived today.
Thank you so much for finding and sending it. I would be pleased to reimburse
you for your time and shipping. Please advise off line, and I'll be happy to
reimburse you. There was a lot of info in there that I was not aware of.
Lots of fun looking at it. Thanks again. Paul Conner

Re: Bad day at the airport
Hi, Mark....that seems to be the
general consensus, and I agree that it is the most likely cause of the fuel
starvation. I ran the aircraft several times yesterday, and it still ran
as smooth as ever. I tried a couple of aborted takeoffs, and it still
ran great. Good acceleration, nosewheel off the ground by 1200 feet.
Unfortunately, until I vent the sump tank and install firesleeving on my fuel
lines, the nosewheel is the only part of the plane that is going to leave the
ground. Will keep you posted. Thanks again for your input.
Paul Conner, off to the welder

Paul,
It looks like the
group has focused in on the fuel system, or more specifically the sump tank
as the likely culprit. I suspected you might have been running mogas.
Its my understanding that auto fuel has a much lower vapor pressure
than avgas and is therefore more likely to vapor lock.
Just a SWAG, but I
think the engine and related systems got hot enough to heat the fuel in the
fuel rails so that once it passed the pressure regulator (pressure drop) it
started to boil, similar to when you open a hot soda. With the return
fuel going to an unvented tank, the boiling fuel expanded enough to cause
pressure in the header tank so as to prevent fresh fuel from flowing into
the tank. Eventually, the header tank ran dry and the engine
quit. You sure handled the situation like a pro. Hope I never
have to face that scenario.

Hi, Mark...my humblest
appologies for taking so long to respond. I am whittling down the 200
plus messages in my inbox. I was using auto fuel (regular). I have a
fuel return line and it goes to the top of my aluminum sump tank that is
located on the cool side of the firewall (inside the cabin, behind the rear
seat). The return line is -8 in size. Hope this helps. Paul
