how do i reco a EF1000is

I love my little generator so much it now needs reco and i am unsure where to start.
Ive loved it 5500hrs or nearly half-a-million kilometers - 10hrs per day by 16months....it now blows blue smoke, needs a carby blow-out every start and glug-oil doesnt seem to work...The plug gunks up reallllly badly really quickly and it uses 180ml's of oil per 2 litres of fuel...

Would i just need a set of rings for it??
