Update!!

The kit that was ordered from Amazon was not compatible. The K20 kit is and I redid both carbs. Got the F7 to the field today for a first run of the engines at stock needle settings 1.5 turns on both H and L needles. The right engine ran great 7800 to 7900 rpms with an 18x8 Xoar idle at 1800 to 1900 rpms with great transition. The Left engine is a problem she started off good but then downhill. Difficult to start needing to choke to get running each time. Spark good it's a fuel flow issue. I richened the L needle out to 2 turns and it didn't help. Sluggish transition and she would abruptly die going from full throttle to idle not a drifting drop in rpms you see when your too lean on the low end. will take the carb apart tomorrow and check it again.
