I have a 25hp that I has been having carb problems. I have cleaned the carb and can't get it to idle. I adjusted main air screw and it doesn't make any diffrerence at all no matter how far in or out I screw it. Could it be possible that there is some crud still plugging the hole where the screw seats? Second I think the timing may be off, is there any way to see if it's close without running it up to full throttle? If I can't get it to run how can I get it to run wide open.....
