Kevin,
The needles may be worn but they should slide all the way into the jets
anyway. The hole in the jet is 90 thou' and the needle at its widest is 89.
It sounds as though you are a little anxious, give the engine a chance to
bed in and then tune the carb's. Too much fuel will do no harm, too little
will!
Cheers, "Bob".
