take a blow gun or compressed air blow through carb where the fuel lines go & then try it

You have an overrich fuel condition.
That will make the Cat over heat and in time will ruin it.
Check for codes
Check for misfires
Check O2 Sensors.
Fix the engine driveablitiy issues, and hope converter is okey. Not likely if you caught it so late ,it is red hot.
A ten year old converter being clogged,would seem to me, to have been helped along ,by lack of necessary maintainance on the engine

Remove the spring loaded screw.Then clean the end of it.Replace it.Screw it in tight and then losen one and a half turns.hope that was helpfull.

Your carbeurator is gummed up. Remove the old fuel and make up a new fuel mix with new gas from the gas station. Then get a can of carbeurator cleaner spray. Three short squirts in the air intake and let it run. Three more squirts every minute or so until you dissolve the partial blockage that is causing your problem.

I just fixed my Echo PB 2100 with the same issue. It would start, run, all throttle openings OK but would not rev-up. It was a dirty/clogged screen on the muffler. Scraped the thick tar off then used Lacquer Thinner to soak it clean. Blower works better than ever now....

TRake the fron grill off and the front board 6- screws on my 65inch there are three adjustment knobs one of them wil adjust the huge
one the whole screen,if not that,I have heard mold growing on and the inside of the blue bulb because it runs the coolest out of the three.
