8n wont throttle up

Matt Southard 52 8N IT WONT GO PAST ABOUT 1/2 THROTTLE fresh tune up, rebuilt carb, cleaned very well, new fuel shut off, new elbow filter in carb, checked timing, clean fuel tank. it will rev up if I pull the power/main adjustment needle all the way out. any ideas would be great thanks
Bob G If the rods are on right, and if it revs up up main jet out, then something is blocked in carb. I would run a ire thru every hole, passage way in carb and then blow air thru each one. assume you have the required fuel flow from bottom of carb. 1 pint in 2 - 3 minutes.
good luck

Matt Southard thanks, rods are on right, throttle moves it just dies at half throttle or up, have cleaned carb will pull it again and run wire thought it. fuel flow is good
