I have a featherlite weedeater xt200, and I have replaced the spark plug, fuel, cleaned the air filter and fuel filter. The weedeater will start for a few minutes and then stalls and will not start for a while. Gas does leak out of the gas cap...

Did you try this with new gas that you just bought?

If so then it's a carb adjustment dirt in the carb or fuel pump

I have an ECHO-SRM-225 and I replaced the primer bulb,spark plug twice now,fuel filter, and air filter. I only use gas with no ethanol to start with. It starts beautifully now, but when I squeeze the trigger, it boggles down and dies... What should I do now?
