Got 2 SS440’s that have been sitting for a few years cleaned the gas tank, carb and put in new fuel line. I got the thing started and once I turn the choke off it idles up to about 3000rpm then bogs our and dies. I’ve tried adjusting the idle screw but it does nothing. When the choke is on I can get it do idle down. Throttle cable is adjusted to the manuals specifications . One thing I noticed is there’s a hole drilled in the bottom of the throttle plate could this be causing the problem? Any help is appreciated.
