Sputter

Does it have an accelerator pump shot,when you hit the throttle?Engine off,air cleaner off.Peer over the carb throat.Wack the carb linkage,watch for two fuel shots.From the squirter cluster.If not,pull carb apart,blow all orifices out with a tip gun,highly compressed air.Not trying to offend,just what I normally see.Some people dip carbs,re-assemble.Anal people,hit every orifice with a tip gun.Best of luck.
