Way rich with stock jets

OK, got the jets out. The 76 carbs (which is what is on it now) have the following:

115
17.5

the 79 accelerator pump carbs have the following:

110
15

The larger numbers were on the end of the big jet in the center where the needle goes down into. I have not seen where the "clip" is located on the needle either.
The smaller numbers are on the side of a little jet beside the bigger center jet.

Sorry, I don't know which ones are which. I am a dummy when it comes to carbs.

Should there be o-rings on the Main Jet's?
Thanks

The 76 KZ900 VM26s didn't have orings on the main jet holder tubes (emulsion tubes) as I recall.

I saw that the throttle range where I am having the problem involves the "needle jet, pilot jet, and pilot tube". How can I check those things, or should I change the needle height?

Thanks,

My carbs are mikuni and the O.D. of the inlet is 1.340" which convertes to 34mm.
If this helps anything

I'm still liking the plugs are too cold suggestion. is B7ES really stock for that bike? Mine's B8ES.
