ok it cranks and idles all day long, but as soon as you give it some gas it boggs down. With the choke barely on it will run if you stay on the throttle.

thus far i have changed plug, cleaned air filter, switched out the carb from the other identical machine i have that runs fine, drilled a hole through the feul filter, and ran a fuel line straight from the tank to the carb to eliminate the shut off valve. none of the things had any effect.

i am running out of ideas! acts like it's starving for fuel, but after trying a working carb and running a fuel line straight from the tank i am stumped... PLEASE HELP!!

check your throttle cable for too much play.there is a switch in the housing called a ETC. if too much play the switch will be open and will not let the motor rev over 1500rpm. it is a safety device in case the throttle sticks open or cable brakes.
