If engine is a twin, one cylinder may not be firing. check by pulling one plug wire at a time. listen for drop in rpm... Also replace Plug(s).
If engine start to pull/run better as you begin to apply choke, yer prolly due for a carb cleaning session. Take carb off, apart, soak(immerse) in carb cleaner overnite, use magnifying glass and run thin copper wire thru all SMALL holes/orifices, blow out all holes and parts surfaces with compressed air, re-asm using fresh carb rebuild kit. Do not re-use any gaskets. Name of the game is to work clean.
