2017 Cub Cadet Challenger 750 - knocking noise?


Recommended Posts

Hello all,

New to the forum, so I apologize if I'm posting wrong.   I bought a used 2017 cub cadet challenger 750 and it has a knocking sound coming from the engine when at idle.  It appears to lessen when reeved.  Is this normal noise?   Thanks everyone.

      Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?
       
      Any help appreciated!

      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL
