2007 Suzuki LTZ-50 Won't move.

[Brantley11]

I bought this LTZ-50 for $50 and it didn't run.

I changed the oil, ultrasonic cleaned the carb, new air filter and now it starts.

The idle is high and I have not been able to change that with the throttle stop screw or the air/fuel mix screw.  It smokes a white smoke and it won't move.

I am not sure if the belt is stretched, clutches are bad, drive shaft and counter shaft are stripped.  I really have no clue.  Any help would be great

Here is a video of it at idle and here is a video of it going from idle to full throttle.

I am sure it is something simple but I am stumped!

It looks to me  like the  clutch  on the motor  is faulty.. As the motor  revs  up ,that  clutch  should  close  up   and grab the  belt..    I don't  see the  clutch  closing up  at  all.

That's the clutch with the rollers. I cleaned the rollers and the cage. I didn't see any flat spots. The plates did have some rust on them. 

 

Could a stretched belt cause this?

I didn't see the clutch closing at  all.. It  should  close  when the motor  revs up  whether there  is a belt there  or not.  At  idle , the  motor  clutch is  open  and the  driven  is closed.. The  belt is slack   so the  motor  can run  without  driving the  machine .. When the  motor revs up, the  clutch  should  close  to  grip the belt .

Here  is  a  youtube video  of  one in action.

Do you think that I need to lube rollers?

 

Could lower compression or lack of engine power cause the clutch not to move out?

 

I'm going to check compression and run it up on a jack to see if it will engage without the wheels touching the ground today and let you know what i find.

When the  engine revs up the clutch  on it  closes up to  grip the  belt.. as the  engine  clutch  closes  more,  the  belt  rides higher in the  clutch. At the same time  the  driven  clutch opens up, allowing the  belt to ride  lower in the groove  to increase  speed at the  wheels.   I   don't  see  movement  in the   drive  clutch  at  all, but I  cannot  point you to the  problem  with it  since I don't  know  its internal  mechanism.
