Some jetting question:

Carb (Hitachi DCZ306 26/30 progressive) E15 has P:#102 S:#135 main jets
P:#70 S:#60 main air jets
#50 power jet

Carb (Hitachi DCZ328 28/32 progressive) E16 carb has P:#98 S:#135 main jets
P:#95 S:#60 main air jets
#45 power jet

(P: primary S:secondary, carbs are not of the hopeless chokeless type)

Would it bring some performance by replacing the E16-carb jets with those of a E15-carb?

A complete chart of all the specifications would help.
But as of right now, no. The E16 is tuned to run "perfectly" the way it is
and changing the jets would throw it out of wack. Not to mention
the primary and secondarys are 2mm bigger.

I'm not gonna change the jets, it works fine that way.
And I don't wanna mess up with those brass jets one wrong move and it's screwed and the same counts for the aluminium housings of the carb.
But thanks PulseMan.
