1572 creeping
 

I know its somewhere on here, but couldn't find it. My hydro on my 1572 while mowing keeps creeping faster and the lever wont stay in place. What and where should I start guys?

I think on the left side of the dash tower there is a rather large nut with a washer under it. Tighten that up until you feel some resistance on the control lever. My 1572 did the same thing as you are describing.
