OK, I know this is probably a total newbie mistake but I just made it, feel free to laugh at me if you like I needed to adjust my idle speed because it was high (3000rpm) and a friend told me to adjust the pilot screw, so thats what I did. I got it running (although not warmed up like I should have) and adjusted the pilot screw on the right carb counter clockwise... nothing happened. Then I tried going clockwise and nothing happened again. So I tried to put it back where I thought I had started from and left it for about an hr. When I came back, it started right up, then the RPMs slowly started to drop and then drop some more and that was the end of it. I havent been able to get it running since. Every so often if I pull the choke out, it will start but quickly (in about 10seconds) shuts off again. I have tried adjusting the pilot screw back to its original point but Im afraid that Im just making it worse. Does anyone have any suggestions for me. Is there a good way to diagnose whats going on? Or is this a common mistake with an easy fix? it seems like its all in the pilot screw since that is the only think that I adjusted. Could my carbs be out of sync since I only adjusted the pilot screw on the right side?
