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? > >I pulled the fuel line off the carburetor and turned the electric fuel pump on and saw about 21 GPH flow.
