| Subject: | Pulsar Reunion update |
Garmin will be attending this year. They will display their products and be
talking about all the new features. I am working with Bing carburetor and
hope they will attend. I am looking for a DAR to talk about inspection and
registration and a volunteer to talk about flight testing. I am moving
forward with planning so will get the official announcement out this week.
Any other topics you would like to see on the agenda?
Take care and be safe,
Greg

Bob,
When you first took the fuel system apart you said that you could not blow
back through the electric fuel pump. You said there was a check valve.
Later you said that you could blow through it in both directions.Doesn't
sound consistent. Is it possible that there is an intermitent fault with
the check valve in the electric fuel pump ? ? ? ?
If you still have it, shake it up, blow in both directions, abuse it to see
if you can get it to behave differently.
Question: Did you have a bleed back line to the fuel cells eminating from
between the engine fuel pump and the carbs ? ? ? Before I put mine in I
would occasionally have trouble starting a hot engine and once had the
engine stop because vapor lock had prevented fuel flow. (( I was still on
the ground.))

*You are right it is a puzzle as to why I could blow thru the 12v fuel
pump both ways after removing it. Best guess it was from the rough
handling removing the pump. Actually there are 2 check valves in the
pump, one fixed and one on the shuttle that moves the fuel. I have the
pump back from the NTSB after they took it apart. I have inspected it
and run it and do not see how it would block the fuel flow. Yes I have
run it in different positions.

On Sunday I went up in a plane Cech factory built - with a 912S and had
mentioned your problem to the owner so, he put the electic pump on for
15 seconds - turned it off - turned the fuel off at the selector -
started, the oil temp came up in about 4 minutes then soon after the RPM
started to die, turned fuel on - electic pump on - and we were away
again, to the holding point for take off ??
