Small Engines (Lawn Mowers, etc.): Troy-Bilt TB475SS, troy bilt, carburetor

Question
This is a 4-Cycle, trimmer with speed connect assec. We use the heck out of it, but keep it clean, clean the air filter, new plug, adjusted valves. Was working fine, then today, will not rev up. You can start it no problem, idles fine, but hit the trigger and it bogs down. Perhaps the 5th or 6th time you try and use it, it will run perfectly for 10min or so and same thing. Tried diff gas, no change. Can you help?

At least we know where to start, I would check the carburetor sounds like the main jet is clogged or obstructed. May be time to have it rebuilt if you do it yourself be careful if you use air sometimes you blow away loose parts you may need later.

Thanks
