912uls Carburetor Part # was created by jiott
In reading thru the new SI-912-032 it refers to carburetor part no. and carburetor S/N. Where do I find these numbers on my carburetors, and do I need to remove the carburetor to read them? Is there a way to get them if I know my engine S/N?

Carb serials are stamped on the side of the carb.



Note: not all carbs actually have a serial number stamp (some of the earlier ones did not)

If your engine is fairly RECENT, (~ last ten years or so) I can look up the carb serial numbers in the factory database, cross-referenced on your engine serial number. ( That's assuming your engine still has the original factory carbs).

Thank you for the reply. My 912uls is about 6 years old, S/N 6779693 and the carbs are original factory. I would appreciate if you would cross-reference my engine S/N to the carb S/N. Access to read the carb numbers is difficult.

Thank you.
Curious-what connection is listed as: "with screw connection UNF"
I thought all threads were metric?

The thread on the engine are Metric but the engine can be ordered with either Metric or Imperial/AN fittings installed in the threads.
The European market prefers Metric fittings and the US market usually gets AN-6 Flared Oil fittings.
Your Oil Tank probably also has the AN-6 fittings brazed in place.
