Sounds like a fuel problem.
make sure fuel is clean and correct mix.
check the fuel pick up is clean
failing that remove the carb and strip, you sould find a gauze inisde, which may be dirty. also check the needle is clean.
good luck

If it's been standing for in excess of 8 weeks with fuel in the system then it's most likely to be stale fuel at best or a varnished/gummed carb due to the stale fuel degenerating back to it's raw state.

You can remove the carb and attempt to clean the jets etc of the carb with a proprietry aerosol carb spray, or alternatively get it ultrasonically cleaned- which is the better option. Whilst you have it stripped it's also worth replacing the diaphragms.

I would look for a defective fuel hose. These will harden and crack after years of service. The 028 has been around for several years.
