Morning all. Been repairing mowers as a hobby off and on for aver 15 yrs but I am stumped with my own mower. The mower is a 20+ yr old (~2004) Honda HRM215K2 hxa which was down to 1 speed (slow). I changed the drive belt and drive cable. For the first 2 mows it worked great (no tranny issue I'm thinking) but now it is back to only slow again. Cable is adjusted properly and there is no fluid leak from the tranny. Frustrating. Belt slipping, pulley?? Any suggestions would be greatly appreciated.
