    did this just start happening out of the blue or did it get worked on first?
    If the solenoid is working then find the linkage going to the carb and work the idle switch and watch the linkage. Does it move the lever on the carb? If so, you may have a loose butterfly in the carb or an air leak but definitely not an electrical problem.

      He's got high idle, no low idle, idle solinoid is not pulling to low idle. He's been replacing parts without knowing whats actually going on, which is ok, pretty sure he has no 12Vdc either from the oil pressure switch or start/run/idle switch.

        jessem, I can't tell for sure due to the photo size but it looks like the governor link is in the wrong hole on the carb throttle lever.

        Governor link goes in this hole.

            Good, eye, he just kept changing parts, so I didn't catch on, making it a throttle issue, whoops, time to get better reading glasses.

                  When assembled correctly, you should be able to pull the governor lever, governor link and idler solenoid plunger all back to the idle position with the engine running by hand as a check prior to seeing if it works properly electrically.

                  Don't forget, when functioning properly electrically, there's an approximate 15 second delay before the auto idler activates after selecting the Auto Idle mode with no load on the unit.

                      Just a simple question can you idle it down manually?

                          OK jessem, Let's set the Auto Idle issue aside for just a moment and concentrate on getting the unit to run smoothly.

                          The 'hunting' or surging up and down sounds like governor sensitivity which is adjusted by the placement of the governor speed spring in the governor lever as shown here:

                          Move the spring location out one or two holes which will 'buffer' the governor reaction and should smooth out the RPM unless you do have a carburetor problem that would require a carburetor overhaul or a cleaning at the very least. The fact that the speed settles down by pulling out the choke a little indicates the carburetor may indeed need attention but try the governor speed spring location first as it's easier and I rarely see them in the first hole as it appears to be in your photo.

                          Let us know.

                            I agree with duane55 the governor adjustment may be out or the governor is seized. Smaller fork lift do the same thing Get the engine to run before other repairs are made.

                              ok no go on switching holes i did look at a diaphram on the side of the carburator its seen better days i think maybe a carb rebuild on this thing wouldnt be a bad isea only thing is it dont know the model number for this thing if looked fopr a plate/sticker and nothing.

                                Well, if you're up for it and have the ability to do it, rather than repost everything that has already been recently discussed on the topic you can check out the thread below regarding a Bobcat carb rebuild including where to get the rebuild kit at a very reasonable price. Get the accelerator pump kit too if you're going to do it.
