Re: so i need your opinion please
What carburetor are you using now?
With no more done to the engine that what you've listed you won't get much better performance than with the good old NT or NT Speed carb. They'll both provide you with good all-round performance, easily tuned and basically troublefree. Just give them clean gasoline and they'll work well for you.
