Sure. The mower needs regular maintenance, and adjusting the drive cable usually has to be done after a few seasons. The sliding handle should have about 1" free play to allow the drive to disengage for easy pull-back. You need to tighten the drive cable. Work the sliding handle and see where the cable goes into a bracket on the fixed handle. You'll find a clamp nut on the plastic clamp bracket. When you loosen the nut, you can pull up about 1/4" of wound steel cable housing. Tighten the clamp nut and check the free play to see if it reduced. Then start the mower and try the drive - it might need a greater adjustment. Or, I may have forgotten whether the adjustment goes the other way - but that's how you do it.

Thank you! I'll check it out.

To improve the drive speed loosen the bolt on the plastic clamp bracked as 1saxman stated, then pull the cable downward, this will increase the tension on the drive pulley. If after making several adjustments and you see no improvement, the drive belt may be strectched or worn and need replacement.

Thanks! I appreciate the input.

Thanks for the help! I never can remember which way that adjustment goes!
