The back side of the carb mounting flange is relieved a bit, to allow the carb to be tilted/pivited out. To get the choke out of the way, hold the choke arm forward and push in on the choke knob. It is spring loaded. While pushing in, turn the knob 90 degrees and then pull it out of the lower cowl. Even with all this, I didn’t say it is easy….but yes, it CAN be done without removing the power head. It does sound like that’s what you need. Although, if you pull the idle tube out of it (Under the diagonal facing plug on the top side of the carb) you might be able to just clean out that tube and try it again.

Long live American manufacturing!
