possible new 720

njwett · 03-15-2010, 05:58 AM

can anyone tell me how to adjust the throttle plates on a 720 hitachi caburetor. I've already turned the throttle plate adjusting screw all the way out but it still doesn't close the throttle plate all the way. I can look down the throttle body and see that the throttle plates are still stuck open causing the truck to idle at 3000 rpm. if anyone can give me some help that would be awesome.

your throttle cable isnt binding anywhere is it? just a thought! Not sure exactly whats going on. Got any pics of the issue at hand? possibly a pic of the adjustment screw and throttle body. a pic of the throttle plate. and anything else you may have done while taking the head off?
