Fund Raiser
Dear Listers,
Bob Nuckolls of the AeroElectric fame has generously put a new eMag P113 electronic
4-cylinder mag up for sale on EBay. Bob has pledged to donate all of the
proceeds from this auction in support of this year's Matronics Fund Raiser.
If you are in the market for one of these great electronic ignitions (I have two
eMags on my RV-8 and love them), please bid on this one!

Thank you in advance!

Hi Matt. My O-360 in my Tiger turns around 2300 on the takeoff run. If I check
fuel flow at liftoff and immediately after I show about 17.5 gph on my JPI.
During climb out since I am at or below 75% power I will lean it back down to
about 14 gallons per hour. EGT and CHT numbers look really nice and low.

| Subject: | Re: Lycoming O-360 Fuel Flow Rate |
Thank you to everyone that responded!! There were some great comments that got
me going down the right path.
Last night I got the cowling back on and took the RV-6 out on the runway and ran
it up to full power with the intent of carefully watching the flow rate and
aborting the take off if the flow wasn't sufficiently high enough. I'm happy
to report that the flow rate climbed nicely up though the teens as my takeoff
roll progressed. I lifted off around 15-16 gph and decided to take it around
the pattern. As I climbed through the crosswind to downwind turn I noted that
the flow was in the 18.5gph range, RPM was at 2700, and EGTs were low 1300's.
After a few more loops around the pattern everything seemed to be working as
expected. I took it out of the pattern and dialed it into my normal cruse configuration
which is typically 75% power at 2250 RPM and leaned to about 1425
on the hottest EGT. Everything sounded and felt fine. Flow was right at 9.5
GPH per usual.
The only weird thing I noticed was at about 1700 RPM. When I turn from Downwind
to Base and go from idle to about 2000 RPM like I usually do, right about 1700
RPM the engine kind of sags and then picks back up. It is very repeatable.
Strangely there is no sag on the ground after a touch and go when I push the
throttle in fast going from idle to full power anymore like there was with the
old carb.
Does anyone have any idea what that sag at 1700 is? Is there a nurd knob on the
carb for this specifically?
Thanks again for the great feedback!

I've replaced the mechanical fuel pump and got a rebuilt 4-5 carburetor, both
of which were well over do for replacement/overhaul anyway. I haven't put
the cowling back on yet, but I did a static run up to about 2350-2400 and am seeing
about 9gph, which seems low to me?
