Check your in-tank pick-up filter. Perhaps you are getting foreign matter in the tank; tip the tank out for a look. If it's cr*ppy, it might be your fuel container has dirt in it, being carried thru as you pour the fuel into the tank. My recently bought trimmer had a hardened/cracked fuel line at the grommet into the tank. Perhaps some of the parts are not all as young/new as the rest.
