You have an obstruction in the "high speed circut" The engine will idle just fine because it is getting fuel through the low speed circut.
Think of it like like a freeway.... you can drive down the right hand lane, but you get get on the express lane because there is an "obstruction" aka accident so until you clean the high speed nozzle and jet you will continue to have this problem.
I have said this many times before, always check on the price of carb replacement BEFORE starting a rebuild. Many times you can get a new replacement carb for under 50 bucks retail. More times then not you end up trying to put a kit in the carb only to find out a couple hours later you need to still replace the carb.
Sometimes no matter how hard you try to clean the carb it just wont work right.
In your case however..if you would replace the high speed nozzle and adjut it out about 1 1/2 turns you should be able to run your engine at high speed. It may hunt and surge, which is yet another problem.
FWIW... No fire on these and the 6.0 hp series is often an indicater that the magnets have fallen off inside the flywheel.
