Picked up a non-running Stihl 028 today from Craigslist. The guy told me that he had the carb rebuilt and it still wouldn't run. The saw was really clean and had a new 16" Rollomatic E bar and chain on it, new spur, new plug, and other stuff I don't remember.
I tried to start it when I got home. No dice. Pulled the plug - it has less than 1/2 thread in there crooked. I put it in straight and tried again. No dice.
I pulled the filter and put my thumb over the carb and after three pulls my thumb was wet. It hit and ran for a second and died. I decided it was time to pull the carb and muffler for piston inspection and a vacuum and pressure test. When I pulled the carb, the paper gasket that comes with the rebuild kits was under the carb. I yanked it off and tossed it in the trash. I then decide to check the diaphragm orientation. Fuel pump was good to go, but the metering diaphragm was upside down. Flipped it over and put it back together. Now it runs like a new one! Not bad for $80.
