"I have had the motor for 5 ye

"I have had the motor for 5 years now and when i got the motor it ran really ruff. The motor would run wide open just fine, but when i would idle the motor down the motor spits and idles lower and then finally it dies. i havent done anything to the motor yet. what is the first thing that i should do? rebuild the carb? I have never rebuilt a carb before so does anyone have a diagram of the carb to help me? thank you for your time."
 
Sounds like a partially plugge

Sounds like a partially plugged idle circuit or carb set too lean at idle. Try some SeaFoam in the gas - that might clean the carb. If all else fails - best to disassemble and clean the carb.
