Lack of power in roybi power head
I have Ryobi CS30 2-cycle power head with multiple attachments. The engine starts without any problems, but has no power after warm-up. It sounds like it is choked all the time. If it were a two cylender engine, I would believe it was hitting on only one cylinder.
To this point, I have removed the carb. cleaned it with carb cleaner. Removed the needle valves and cleaned with carb cleaner. Inspected for full opening of the choke and throttle. Checked the gap and ensured it was at .025. Replaced the fuel with fresh fuel/oil.
I checked for an obstruction from the fuel intake line, and it flowed free. I chedk the fuel cap to see if it was clogged, and it appeared ok. (The engine ran the same with the cap on or off) I made sure the air filter was clean.
I adjusted the low speed needle valve to 1 rev from closed and the high spead to 1.25 rev from closed. It starts fine, and fine adjustment on the high speed needle valve only marginally helps.
This thing is only two years old and it should not be worn out at this point in time.

Take a look at other things that are affected by the muffler. Is it touching the plug wire (maybe a rubbed spot where the wire is shorting against the muffler?)? Maybe it's touching the kill wire for the coil?
