MY TRAILBOSS 325 STARTED GRINDING THE OTHER DAY. FOUND OUT MY FRONT SPROCKET HAD ABOUT 1/4 INCH OF PLAY FROM SIDE TO SIDE. IS THERE SUPPOSED TO BE A RETAINING CLIP OR A SPACER ON THE ENGINE SIDE OF THE SPROCKET? THERE WAS ONE ON THE OUTER SIDE OF IT BUT NOTHING ON THE INSIDE. ANY HELP WOULD BE APPRECIATED JUST SO YOU KNOW I KEEP MY CHAIN ADJUSTED BETWEEN 1/8 TO 1/4

 

There is a retainer on the outside only. The sprocket is allowed to "float" some. Are you sure that the trans output shaft is not moving in and out or is it just the sprocket?
