Yesterday and today I had time to check out the
regulators and the injectors, all are working, had to put a four foot extension
on the stethoscope to do this alone. When I was installing the fuel bypass
tubing there was much discussion, here, on the size of tubing to use,
the directions with the Mallory regulator states to back out the adjusting screw
and run the pumps to see if there is restriction and with the 5/16" tubing the
pressure came to 3.9 #'s, a little more than Lynn stated that the Weber can
take. It would take a month of Sunday's to change the by-pass hose and
fittings to -6 size, so I guess I'll install the after market needle
valve. The project started out with the 48 Weber and Tracy's electronic
ignition system to fly 4 years ago and eventually install the fuel injection as
a winter project at a later date. Life gets in the way of living and plans
change, so l have both carb and fuel injection, using the Weber as a throttle
body, or carb, if the injection system fails. Enclosed are two photo's of
the carb, over the top manifold, with the fuel injection hidden beneath the
intake manifold. My machinist buddy made two plates of aluminum to level
the carb on the intake manifold.
How long on the average do you need to run the
engine in 50 degree weather before it will stay running with the cold start
switch off? (fuel injection) I will need to add several items on the
after start check list, as in all the excitement many things were overlooked and
in all this checking, you notice things that didn't quite get finished as
distractions arose, there is a positive note in every thing.
That gasohol is some nasty stuff, it looks like a
cloud floating around in it and I got some on the pressure gauge face and it
turned it to slime and when it drips, it looks like olive oil and the odor is
terrible. JohnD
