I recently ordered a 22mm Mikuni (this one) and a couple of diffrent sizes main jets (these) and a Pilot jet (here).
Package arrived this week in good order, and the extra ordered main jets, don't seem to fit this carburator (slightly different thread-pitch)
When I measure the main jet thread size that came in the carburator, it is M5x0,8 thread, with a 8mm round head.
The extra ordered main jets have a 6mm round head and their thread size is M5x0,75.
The pilot jet does fit and this is M4x0,7 thread.
Is this a common problem? Or does anyone just screw in the main jets? And screw up the thread...
According to the jet description, the jets should fit.
There's a very little hole on the intake manifold site, under (and outside) the rubber O-ring gasket. What's it's use? If bolted to a manifold this small hole will be blocked. If I would make a manifold where this hole enters, then it might leak, because the hole is outside the 0-ring gasket.

Main jet used in Mikuni RS and HS carburetors, and small body Mikunis.
Fits Mikuni Small Body 22mm thru 26mm Round Slide Carbs. Also used in 33mm Pumper Carbs
Small Body Carbs are used in OEM applications. Also referred to "Chinese" Mikunis (though not always true) or new style Round Slides.
These are also what is typically used in Mini-Bike & karts due to the lower cost
