A big THANK YOU to everyone for suggestions. I installed a DLE20 carb and the engine ran just fine. I don't have a spare DLE30 carb so I may order one from Tower. They are about $35.00. The prop on this plane was a Zoar 17X6 which is usually great for a 20cc engine. I don't actually know how many cc's but I believe it is 20 to 26cc. I will get it tuned up to check for top rpm and then compare it to a DLE30 carb to see which it likes better.

I'm quite sure something is wrong with the original carb, a Walbro WA197A. I took it completely apart, sprayed all openings with regular carb cleaner. I replaced everything with new components except for the metering spring which was not included in the K10WAT overhaul kit. Re-assembled making sure everything was in the correct order. I loaded the pump side with fuel before putting on the cover with the four screws. I also blew gently into the fuel line and depressed the metering lever. It allowed fuel to enter the chamber.
Although I will be satisfied by replacing the carb, my appetite for knowledge makes me want to find the problem with the faulty carb.
Thanks agin for all the suggestions. I'll report which carb, a DLE20 or 30 works best. I just placed the order from Tower for the 30.
