Where should I buy the replacement carburetor? Is there an upgrade to the current Walbro WGA-7?

Mike,

I may have over tightened the parts, but I also put gasket sealer between all the surfaces. I am very confident that the assembly is sealed. I did mix the Ams Oil 100-1 at 50:1. There was no change in performance from the 90:1 mix. I have used the 100-1 mixed at 90:1 in my G-62 for years. I also ran the 3W-140 on this mix for over 30 flights with no problems. I just don't think the carb is letting enough fuel into the engine.

Thanks for the help,
Cliff
