I have a Murray Riding Lawn Mower that I have been working on. I lifted the mower up to do some work under it and when I left it back down I noticed I had oil coming out of the air filter. cleaned up the oil and tried to start. Started for a second then started to click. Got under the mower and turned the shaft from the engine, Can only turn a bit both ways then stops. Any Ideas how to fix so that I can start the mower again?

I have a Craftsman chainsaw model# 316.350840. From what I can tell from looking up parts, it is a MTD 41AY85AR799, which in turn, may be actually a McCulloch chainsaw. I removed the carburetor and gave it a good cleaning, and after I put it back together and tested it, the motor runs at full throttle without pulling the trigger. There is an arm on the carb that is supposed to come in contact with the idle screw, but it doesn't even come close to the screw. It does when the carb is lifted out of the housing, but once I push the carb back in (putting tension on the throttle cable) the idle arm swings away from the screw. I can push it to the screw with a bit of force, but once the trigger is pulled and released, it does not return. The sleeve sleeve of the throttle cable (part MC-9010-310201) does look a bit beat up, and it is torn right at the tension clamp thingy. Problem, is nowhere has it for sale. The parts diagram on the Sears parts site is really low res. This parts page is identical and higher res: [url=http://www.bendlelawnequip.com/pages/oemparts?aribrand=SMP#%2fMTD%2f41AY85AR799_(316.350840)%2fGeneral_Assembly%2f0800014-A%2f08000140001]OEM Parts[/url]
