ran another two tanks today ruch settings friday i plan to lean alittle and run two more. nothing unusual idles all day long no problem though. I open the idle screw 1/2 turn during start up let it sit 30 - 45 seconds short blips to warm in up a little and once it warms return the idle screw to its original setting, once its warm it will idle for minutes with a little hicup under aceleration. I'm gonna lean the top a little and let er rip!!
