I have a Husqvarna gas-powered weed whacker. Starting late last season, it tends to die when given full throttle. Now, it will start when on full choke or half choke, but once I put it in normal operating mode (after warmup) it dies.
It's using gasoline that has the oil mixed in, but the gasoline is rather old. Could that be a factor?
Is there something I can do to fix this myself?
It doesn't take bad gas or ethanol to crud up tiny carb jets and orifices. Any gas gets old and any gas dries into varnish over time, especially that which has been mixed with two-stroke oil. Proper storage is critical.
Seek out an exploded diagram or a how-to and disassemble your carb. Make note of all screw settings (count turns to fully seated) and take some phone pics and clean everything thoroughly with solvent. It'll run better than new.
I have had trouble with small motors since they added methanol to the fuel. the methanol breaks down many of the rubber seals and then the residue gets stuck in the carburetor filter screen. A can of carburetor cleaner and a few minutes to disassemble and cleaning may bring it back to new. Fresh gas is always a plus for small single piston motors.
