minor diffs in flow path can make motor from same factory with same type of carb run better with diff jets - run with any one you find that works for your machine

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.
