I have a 3MM 53, it's my first gas engine. It starts easy, runs up smoothly, and idles well. When I try to throttle up from idle to wfo quickly, it'll cut out and die. If I catch it quickly enough and drop the throttle, the engine will pick back up. I don't have a manual as I bought it from a friend. Am I too rich or too lean? It's dark now and I can't experiment till the weekend...maybe one of you can help me save some time and do it right the first time.
