1711 carburetor

[rswartz]

I'm not sure whether I have a Kohler or Walbro carb on my 1711. Anyone???

According to the Parts lookup, it could be one of 2 options and both look to be Kohler carbs to me.
The 1711 is pretty much the same as a 782.

It's probably supposed to have a Kohler carb, but who knows what somebody's done since it left the factory.

If it is a Walbro it will say Walbro on the side. Also, the main jet in a Walbro is short, and long in a Kohler carb.

Got a picture?

Thanks, Charlie. I had already looked at the parts schematic, but still couldn't come to a conclusion. My carb only has 2 adjusting screws. I don't think it has any writing on the side.

Then it's not a Walbro.

Look inside the throat from the outside in and see if it has a number at the top inside.
That will tell you for sure.

I was wrong guys. I did find Walbro cast into the side of it. Can't figure out why it only has 2 adjusting screws. All schematics I have seen show 3.

I'll say it again, can you post a picture of what you have?

If I remember correctly, the early Walbro carbs have idle and high speed mixture adjustments, plus a idle speed adjustment. The later ones have a fixed main jet, so so only idle speed and mixture adjustment screws. Sounds like you have the latter.

I'll try to get a photo soon, Matt.
Thanks.

Here's a pic of my carb. Besides "Walbro" being cast into the side of it, I also found "WHC".
Let me know what you guys think.

It appears that is the later version of that carb with the fixed main jet. If you go in the parts lookup and search for an 1811 or 1862 you will probably find the same carb.

Edit: Or a better idea would be to get either a #26 Kohler carb, or KT-17 series I carb and replace it. I'm pretty sure you can use the throttle and choke shafts from the Walbro on a #26 carb.
