Engine wont idle just shuts off

Thanks to everyone who helped me yesterday. The two screws I adjusted that was wrong was not on the carbs. If you twist the throttle handle you will see apear from under the pipes on the left side two adjusting screws on the throttle linkage. The service manual does not tell you that the idle adjustment is on the right side. I was successful in adjusting the idle speed but I had to max it out. I will re-adjust those two screws on the throttle linkage back to where they were , siphon the gas out of the gas tank, put new gas in and put some sea foam in. If I notice the idle has increased I will adjust as needed. Thanks agian, I can always count on your help.
