The carb on my 190XT is missing the idle jet and idle speed screws, at least I'm pretty sure.

Is there a super complete kit that would have these, or is there a better replacement (zenith)?

You have a Holley ??    I'd imagine accurate parts would be difficult to come by, but I could be wrong.

I guess not. It looked like the manual so I didn't question it.

Bendi9c 2-101?

Is this worth keeping or is there a better/more standard carb that I can replace it with that'll be more serviceable?

I see the idle mixture screw. It isn't missing. The idle speed screw on the throttle shaft on the back side towards the eng block?? That would be a simple machine screw from a hardware store. An Idle jet ?  ?? that's internal...  Does the tractor now run ??   The numbers you give are a casting number which means nothing.   Zenith 13303 and   62AJ12 do mean something. There is a place called The Carburetor Doctor that can fix you up.

I guess my issue is I don't know what carb this is so I don't know what screw is which or which direction to turn them. I have no manual.

There's this tag on the back? Does that say what carb this is?


I see the main mixture, but no idle mixture. This screw on the front is not a mix screw. Idle adjust may be on the back but I didn't see anything.


It doesn't idle. And doesn't run well. The carb needs rebuilt or replaced. But I can't tell what carb this is, it looked enough like the manual I just assumed it was what the manual said it should be.

I'll check the carburetor doctor. Thanks!

I told you what it was with the numbers I gave you. The angled adjustment screw is for idle speed mixture and normally is 1 1/2 turns out. The other screw holds the venturi in place and is a nothing burger for you. Main jet is fixed/non-adjustable and is in the bowl. Zenith/Bendix is the brand.
