How to adjust idle on 1998 chev surburan


completely remove the air cleaner assembly off the top of the engine and find the throttle body linkage area..its where the gas pedal cable and cruise control hook in..behind this linkage is a small threaded stud with a nut on it to the backside of the throttle body..loosen the nut and turn the stud until the desired engine speed is reached..normally 650 rpm to not much over 850.. too high and the truck will pull at stoplights making you ride the brakes too much..

To install:

  2. Connect the spark plug wires.
  3. Install the PCV valve and pipe assembly.
  4. Connect the brake booster vacuum hose.
  5. If equipped, install the cruise control cable assembly.
  6. Connect the throttle cable and secure the cable support linkage. Tighten the bracket bolts to 10 ft. lbs. (25 Nm) and the bracket nut to 22 ft. lbs. (30 Nm).
  7. Connect the air duct to the inlet, then connect the negative battery cable.

Need to know how to set the throttle so can turn off with cable control instead of having to pull spark plug each time


I need more details to answer this with one statement, but I will give you some solutions based on my experience.

Newer lawnmowers have a dead man lever which will either shut the engine off immediately or stop the blade by the use of a clutch system. If it the dead man lever, it just needs to be released. If the engine has the blade stop, then the throttle cable would control killing the engine. If the mower is really old (>20 years) then the only way is the throttle cable.

To adjust the throttle cable:

Follow the throttle cable down to the engine, it will terminate by the carburetor. There should be a single screw where the cable attaches with a clamp that goes over the cable. Loosen this screw and you can adjust the cable forward or backward to adjust the position (ever model is different based on throttle cable and engine configuration). You can figure the direction out by pulling the lever to the slow speed/off setting and watch the motion of the cable at the carb. If the cable pulls inward then you have to move the cable assemble away from the carb. linkage. This will allow the throttle linkage to pull closed further.

If you pull the air cleaner off, you should be able to see how the throttle linkage and cable interact. There is a ground wire that connects under the linkage, which when shorted out kills the ignition system and the engine turns off. If this wire is not in place or something else is preventing the wiring from shorting out, you will not be able to kill the engine no matter how much you adjust the linkage. If the wire and switch seem to be in the correct place and the throttle linkage is working, but it still doesn't kill the engine, just short the wire out directly to a clean metal surface to verify the condition of the wire.

It runs wide open all the time im wondering where idler arm setting is at


It sounds like the govenor spring has become disconnected or the clamp on the governor shaft has become loose and allowed the linkage to get out of adjustment. If problem has occurred suddenly it could mean the governor gear assembly inside the engine has broken and means the engine will need to be dismantrel to replace the governor gear assembly.
Check throttle linkage to see if spring is attached at both ends, one end on the throttle linkage and the other at the fixed point on the engine or to the end of the speed control lever. With engine stopped the spring should hold the throttle wide open and hand pressure on the linkage shoud be all that is needed to move throttle shaft closed to the idle position with no binding in the movement of the linkage.
If spring is OK and while engine is running, linkage should be able to be be moved to bring engine back to idle. If porblem has occurred gradually, then linkage will need re-adjusting. Loosen adjusting clamp on governor shaft, then holding linkage in wide open throttle position rotate shaft as far as it will go in the opposite direction to that requred to close throttle to idle . Re-tighten clamp.

Gas pedal sticks


does it stick in the cab or on the throttle body? make sure the cable is wrapped around the throttle linkage properly first and then id spray some wd40 on all the moving parts down by the pedal. sometimes gunk can get built up in that area and it just might need a good cleaning. odds are pretty good that the moving parts are really dirty or the cable isnt lined up properly on the throttle linkage. id start there.

Throttle/ govern linkage placement


I would recommend that you go to a store -- with a digital camera and notepad -- that sells this product and has a display of it fully assembled, and take pictures and note on the throttle assembly.
As to the gentleman who did not receive a response on his rating -- I'd like you to know that I certainly appreciate your expertise and time taken to help others out.  People like you inspire people like me to try to help others.  A lot of people go through life never leaving behind anything of good or value to others -- but you can know that you have.  Personally I feel a reward in that.

Throttle body linkage worn?


other than to say he couldn't adjust it because one or the other would be off. Does this make sense? If so it appears Ducati doens't sell the the linkage separately only the complete throttle body assemby with a price tag of $2300 (up here). I did find a 2004 999s throttle body assembly on ebay: http://cgi.ebay.com/ebaymotors/DUCAT...3286.m20.l1116 Looks a little different from mine, but I thought the 999 and 998 are supposed to be the same motor. Can anyone tell me with 100% confidence that it will fit an function without significant modification? Or at least if the throttle linkage can be transplanted?,The linkages are different between a 998 and a 999. From what I can remember you can make them fit but with a hell of a lot of mods..... people who have done it may help. Also check out Gotham Cycle breakers in Florida, he had a write up between what models can be transplanted. (Dont have the link sorry) The linkage is worn????? Can you post a picture to show which part he thinks is worn please? By how much will they not sink? Is this on vacuum check or on CO check of each cylinder? Has he done a TPS reset on the setup? Does this guy have a DDS unit? (Basically a hand held computer to check the brains of the bike) Is this being tested with new spark plugs fitted?,,,
