Re: carb or reed
Hitting the choke button, richens up the fuel air mixture. Two common cause's of this are :
#1 dirty carbs. So if you got a kit, changed out and cleaned behind the welch plugs, de gunked up the fixed jet and cleand out the low speed jet. Reset the float replaced the needle, cleaned out the bowl etc,then you cleaned the carb, other wise, try again.
#2 air leak, so if you did all that, then maybe the carb is sucking air in between the carb throat and reed cover plate. that would be a poor or leaking gasket.
