<><><><><><><> <><><><><><><> Steve, Wear eye protection!!! Maybe take the straw from the spray carb cleaner can and put it up the pilot screw hole. Give it a good spray and while spraying withdraw the straw. Maybe the hydraulic action will move the washer and o-ring out of the hole. I've also had to fish out the washer and o-ring and have had success with the above method and also had to use compressed air. And I've used a very very fine wire with a small hook bent on the end and fished them out. My suggestion to the running issue is you've got it figured out with either the main jet or the needle jet being partially clogged. Make sure you didn't put the needle jet (part #13) in upside down. It should stick up into the bore of the carb just a tad. Also make sure the you have the jet needle and the spring seat (parts #26 & 27) installed correctly. Folks have reported installing them incorrectly and having goofy running issues too. But I think those issues are usually at lower rpms.
