need help

[plummer1111]

i think i have a jetting problem. when i start the quad it will sit and idle fine, rev up fine but as soon as i start going it is like im trying to take off in third gear. if i pull the choke it will take off just fine. could some body point me in a direction that i need to go.currently i have a 50 pilot 148 main

You are too lean if the choke makes it better. Try one clip farther down on the needle. The main would be next go up one size try it then go up again. You need more gas less air.
