The shop I take my lawn equipment is behind a month on trimmers so I cant take mine to them.

My trimmer will idle but once I give it gas it dies. Ive changed the spark plug, gave it new tubing and bulb. Cleaned the carb and filter.

The guy at the shop says over time soot/black stuff will clog the muffler and it will need burned out to clean it. I do not own a blow torch. Anyone on here that can give me a hand with this?
