Help diagnose this Husky 351

[Coach]

Can you guys give some advise on this Husky 351. Starts and runs good, but bogs down easily.  I don't have a compression guage, but piston looks fine, not scored.

Can the clutch be part of issue?  Or just replace rings and see what happens?

Start at the muffler screen and work your way back to the carb.  Clean all the carbon out of everywhere. 

As long as the compression is good it should run well when your done with the service.  The carb will need new diaphragms/gaskets, new fuel lines and a new air and fuel filter should also be considered.  Good luck with the project and if you get stuck or come across something your not familiar with post up your questions and pics so we can help you get through it.
