Greetings Ferocious Frankie :-)

Turn your high speed needle all the way in (GENTLY) (turn to the right) then turn the needle out 2 full turns (turn to the left).
Check your radio and carb before cranking, ensure that the carb is only slightly open and low idle setting on your radio.
Make sure that you can close the carb with your radio all the way.
Have someone hold the airplane and you start your engine.
Allow the engine to warm up before adjusting anything.
If it cranks rev up the engine and see if it will take full throttle without cutting out.
If it will not crank, turn your high speed needle (turn right) just a few clicks until it will crank.
Once you have a reliable engine run at full throttle pinch your fuel line just for a few seconds and listen to your engine.
If it speeds up turn in (right) just a few clicks.
If it cuts out, turn (left) just a few clicks.
Tune your engine until there is no change when you pinch the fuel line.
Then turn your needle (left) just a few clicks to leave it a little rich.
Once you have the high speed set and there is a good transition from idle to full throttle, no hesitation, have someone take the airplane and turn the nose up slightly.
Put you plane in the same attitude as takeoff and listen to the engine, if there is no hesitation then you are ready to take her up.
You need to make sure the engine is ready before takeoff.
LOW END NEEDLE Setting is set from the factory and should not be adjusted unless someone moves it before the engine is broken in.
Once the high speed is set and if you need to check the low end, allow the engine to warm up and with the engine at idle, pinch your fuel line and listen, if the engine cuts out the low end is lean, if the engine speeds up then your too rich.
When you make engine low end needle adjustments you need to BARELY move the needle LESS THAN YOU DID ON THE HIGH end needle setting.
Facing the needle RIGHT is lean, Left is rich.
If you adjust your low end then you need to go back and recheck your high side ((AGAIN.))
