Jetting a carb isn't as easy as that!!
Every engine runs differently (& needs a different size jet to run at it's best).
Your best bet is to buy a complete set of jets & experiment with it... but be very careful not to jet it too small because it will feel like it's kicking a$$, but it will also be burning up the piston dome!
I like to slowly jet one size smaller & stop right when the 'sputtery' feeling stops... this way you know it's still closer the heavy side.
