Mikuni 44PHH Jettings "straight from the horses mouth"
I wasn't sure if this was already out there but I'm certain this is useful information:

Data I've had for a bit from an old Mikuni catalog. This is for a stock 12A mind you.
I've included the jettings for Toyota's 2/3TC motor to illustrate the stark difference of air/fuel consumption between just a stock 12A rotary and say a 1.6/1.8 4 cyl, reciprocating motor using the same carburetor.
No, Mikuni does not include a jetting kit for the 12A employing their 40PHH carb. If you're wondering why then you'll have to read between the lines for the answer
.
It all the more shows how the rotary is "taxed" incorrectly when classifying it's displacement with traditional reciprocating plants.
Enjoy!
