Also, can anyone find this manual for the OS32SX-H(K) series?

I've got one, too. The first half of the manual is Japanese, and it shows the 32 with both the 3H carb and the 20C carb, as well as telling you how to adjust each.

Is your 32 by any chance a ringed version, and does it have the small 3H carb on it?

I'm wondering if this particular 32 that came with the "K" manual didn't come with one of my Kyosho Caliber 30's six years ago. It was a ringed version, and had the 3H carb, as that was how Kyosho and OS marketed the 32 in the Caliber 30 early on. Perhaps the "K" indicates Kyosho. The manual itself talks about the 32 SX-HX (has the pull-start on it), the 32 SX-H ABN and the 32 SX-H Ringed version, as well as both types of carbs.

If you have the 3H carb, put the 20C on it, you'll get a huge increase in performance. If it's the ringed version, no sweat, it has the same power specs as the ABN version.

Other than the manual and the goofy 3H carb, you can't tell the difference between the "K" and the rest.

Dave, I have two of them and they both came with my Caliber30's
They are the ringed version with the 20C carb.
One thing I would like to know if you can answer.
The page I am about to post had somebody telling me I was incorrect about tuning and realigning the mixture control valve 2-1/2 turns from the closed position.
I know the manual via the internet does not show or have this page in the manual.

I just sold that heli, the OS 32, and that manual that I had last night. But my guess is that those particular instructions are for the 3H carb, not the 20C.

The 20C carb has different instructions for resetting the mixture screw (most of us usually call that the low-speed needle, rightly or wrongly). Since you have the 20C carb, go by the instructions you find in manauls on the web for the 20C. It involves sighting down the carb venturi and adjusting the screw until the stepped down shoulder of the needle valve is tangent to the carburetor barrel.
