Zenith Main Jet on 130

Should this carb be equipped with a main jet?

It has an idle jet.

There is a place for main jet.

The IT manual however, tries to make a liar out of us. In the parts list for a 100 carburator it lists only an idle jet. Then under 130 and 140 it lists both idle jet and main jet. The manual also has a conflict as my 140 has a completely different carb from my 130. I couldn't read the tag on 140, but as I recall from installing a kit 3 years ago, Marvel-Schebler sticks in my mind.

The Carter carb on my Super A is much the same design externally as the Zenith on my 130. The carb on my 140 doesn't even look close. IT book indicates only 404 and 2404 have Marvel-Schebler carb. There are 11 different carbs listed in this IT manual for 100, 200, 130, 230, 140, 240, 404 and 2404. Two are for kero and distillate engines one Carter and one Zenith, two each a Carter and Zenith for 100 and 200 tractors. I'll leave you with that as IT are not using same numbers for carb as you have.

One reason I ask is, there is a piece inside the carb that looks like the inside half of the main jet, but only a plug located in the hole.

Be patient, take Deb for a nice long walk through that nice evergreen forest you have up north. Hopfully Canada Post wont be using pony express and by Fri. you should have this IT manual. Then you'll be able to sift through this and hopfully sort out what you have and what you need.

Thanks again, I will take real good care of your manual.

Today would have been great day for a walk, should have taken it instead of raking all those leaves and cutting brush while Deb was tending to the turkey meal. Supposed to get some snow next Sunday!
