My Friend has just bought a Goddon Majesty TY250, it had been stood for several years, we have cleaned carb & tank out & put in fresh petrol, started up no problem, ticks over all good. However took it out on his practice track it seemed to pull Ok but power is very flat, not as good as his Ty175. Starts, runs, does not miss, just seems to lack any Oomph.
Any Ideas ??
