John Deere manages to make things difficult. Even the most basic task of adjusting the valves was way more difficult than it had to be. The carburetor float bowl is in the way of getting the valve cover off, so I had to drop the bowl. The large stem poking down in the photo is what the bowl nut threads onto. That stem is still in the way to get the valve cover out all the way but there was just barely enough room to do the job. I suppose since the carburetor on this tractor is not the correct one, it just might have been easier if the right carb was in place, but I doubt it. Most of these DLTX carburetors are very similar in construction.
