well i guess it ok if it will turn that prop in the 7k range.but why is it like bogging down when going past half throttle?
i have tried it yesterday though and it seems ok, i was able to go full throttle and sounds ok, seems to go along ok without bogging down. i havent change any H needle settings yet. it was in the evening so i guess it has to do with the needle set too lean.

bob i guess thats wats my problem, when going past half throttle the engines slows down and then dies.

if i am to buy a bigger carb, is it available for commercial use? i mean, are there bigger carbs out there that are direct replacement for blowers or trimmers or chainsaws that you can readily buy at the engine shop or at engine parts dealer? because hobbywise, i will never be able to buy it.
