372 lost power

[Happy Trees]

Need some help, I have 20 year old husqy 372 that starts fine, idles and revs normally, but when I start a cut it bogs down and loses all rpm’s. Any advice? It’s fully cleaned out with new mix in the tank.

Husky might be starving for fuel under load. Even with fresh mix, a clogged pilot or main jet, or old fuel varnish in the carb, can cause bogging when you cut. I'd check the carb jets and passages, make sure the air filter is clean, and confirm the spark plug is the correct heat range and properly gapped
