My craftsman 32 cc weed trimmer has ran great for 5 years. Now it doesn't always start and when it does it only runs while on 1/2 choke. As soon as I press the trigger it floods out and stalls. I replaced the spark plug but no difference. Fuel filter? Adjustments?

Its running lean, so you are looking for fuel starvatiopn, blocked filter in the tank, cracked or broken fuel hoses, dirt in the internal carb screen, as a last resort screw H and L screws out by 1/4 turn steps, up too 1/2 turn on each, this will richen the mixture.
