How's the iStart unit working for you?
This has been my first fuel injected engine. Thankfully I've been able
to stick to a single set of procedures for cold and hot starts:
- Cold: Crack throttle 1/4" or so, turn on boost pump until (tunnel
mounted Flowscan) fuel flow meter shows a constant value, then open
mixture for 5 seconds or until flow meter shows constant value. Then
close mixture. Crank until firing, then open mixture to any running
value desired.
- Hot: Crack throttle 1/4" or so, turn on boost pump until (tunnel
mounted Flowscan) fuel flow meter shows a constant value, (delete),
Crank until firing, then open mixture to any running value desired.
The Hot Start procedure works on hot Carolina days, even trying to
re-start seconds after shutdown. If the mixture is accidentally opened
before cranking, the engine floods and difficulties are encountered.
I hope the procedures continue to work after I relocate the Flowscan unit.

Thanks!
It looks like the transducer is 'unmounted' in this case and just
supported by the fuel hoses. I'm thinking of doing the same. Anyone
with experience using a fuel hose supported Flowscan?

Yes,
I went through the same thing after talking to Don @ Airflow, I have the
Floscan and "mounted " it @ the front corner of the engine case
http://deemsrv10.com/album/Sec%20FF4%20Fuel%20System/slides/DSC04976.html.
I used a mounting bracket fabbed out of alu similar to:
http://deemsrv10.com/album/Sec%20FF4%20Fuel%20System/slides/DSC04980.html.
I ordered 2 new hoses to replace this:
http://deemsrv10.com/album/Sec%20FF4%20Fuel%20System/slides/DSC04978.html.
The hose the connects the servo and the flow scan has a right angle fitting
where it connects to the floscan. There is a caution some where about
avoiding that, but the configuration works flawlessly with no fluctuations.

I have been researching alternatives to Weldon which seems to have gotten a bad
rap from many. The alternatives I have seen on various posts include Sika flex
295UV (most popular?), Hysol EA9360, 3M 2216. One I have not seen is the product
used by Cirrus and apparently made specifically for windshield and canopies:
PPG PR-1829. Anyone have experience with the latter?

Thanks, that helps.
Regarding the 90 degree fitting; the 90degree fitting shown on your old
hose is the "full flow" type according to Don@Airflow, and that's okay.
The fitting you want to avoid is the 90 degree fitting where there is no
curve. That type of fitting will impede the free flow of fuel. (I'm
just repeating what Don told our class a few weeks ago).

I just glued in my door windows this past week, and used Lord Adhesive
7545, parts A & E. It was very easy to use, no running and squeezed out
nicely around the edges, filling the gap between the window and fiberglass.
IMHO it doesn't get any easier that that.

Bob,
Rick is dead on. Call Geoff at Aerosport products as he provides the Lord adhesive.
If building again, I would use to glue the door halves together as well.
