Throttle appears to not be functioning properly.

The throttle was and carburator were adjusted properly, however I had a hydraulic leak under the steering column. I had to loosen some hydraulic lines including a small line going directly into the steering gearbox. After i did this the throttle rpm was significantly reduced and the throttle lever does not have any resistance. any suggestions?

SOURCE: how to repair steel hydraulic lines

You should NOT weld. braze or otherwise join, or "fix" an hydraulic lines, they, ideally, must be run as a single length again, any Join will simply fracture... Also if they are developing "Pin Holes" this is probably due to the material breaking down, and like a "Cancer" it will simply spread, and fail at a probable inappropriate time, not as though there are any good times? As an aside there are "Joiner" kit available for hydraulic lines, perhaps, cutting and rejoining like this may be acceptable? but still i wouldn't risk it, run new ones.

SOURCE: John deere 68 riding mower steering column won't

Just had same problem with my craftsmen. There is a very inadequate little nylon bushing supposed to keep that shaft stable. When worn out it allows that shaft to move and puts the gears in a bind. It is located on the end closest to arced gear where shaft hooks to drag link. Its a pain.

Testimonial: "sounds good will try to fix it thx"

How do I adjust the carburator?

There are two needle screws that can be adjusted to make the engine run properly. Be certain that the carburetor is clean and the diaphragm is in good condition, and the fuel is new. The two needle screws mentioned above should initially be adjusted at one turn open from turned in all the way (lightly seated). Each of these needle screws performs different functions. One is for idle and throttle response (this screw is marked "L" and the other screw is marked "H". L and H are marked on the carburetor body and also on the plastic "shroud" near the adjustment screws. These screws are not interchangeable, being foolproof since the thread sizes are not the same. When properly adjusted the low speed screw (L) allows the engine to idle properly and throttle response will work properly. When the high speed screw is adjusted properly the engine will have correct power at full speed. Adjust the low speed screw so that the engine idles and when you squeeze throttle all the way to wide open the engine should not hesitate and should come up to full speed and when you drop the throttle it should idle nicely without stalling. Now adjust the high speed screw. Hold throttle wide open, holding it there while you adjust the high speed screw. If this scares you (be carefully so that the spinning chain does not cut you!) you may adjust the high speed screw at idle, turning it just slightly in or out. The high speed screw should be adjusted so that the engine does not run clean at wide open throttle but sputters slightly, slightly adjusted open from running clean to slightly sputtering. When under load (cutting a log) the engine should run clean. Good luck!

Engine goes off when changing gears from P to D or

check engine light is on? if yes, You need an OBD scanner to dianose the problem. if no, its a mechanical problem. 1st, check if their is a vacuum leaks using the carburator cleaner to spray all over the emission, carburator, the vacuum lines if the idle going up you found the leak, now if still don't work, check if the fuel injector if not failing, check also the fuel filter and cracks on the exchaust manifold.
