I will get to the point. A friend has a Mantis it had been setting up for some time and of course it has mixed fuel 50 to:1 . This is a 2 cycle engine and I believe the problem would have been simple if my son Mr. fix it hadn't have taken the carb off and the plastic cover;s on the carb adjustment. now it will act like it will start, you hit but want run. I cleaned the tank filter and the gunk but haven't pulled the carb. Maybe I should and perhaps get another carb or get a kit. If I do what is the adjustment to start with to at least to get it to run. It acts like its not getting fuel and I believe its not. Do you think the reed is messed up. What or where should I begin First ?
