don't feed them ethanol gas? Went through 2 Lawnboys (FWD), 2 Toros (RWD), now have a Honda (RWD) that starts every time. I have heard that when the tranny goes - get another one. Now that is for 40 yrs of mowing. Lawnboys had carb problems and I got them for $20 used from a buddy that was a OMC salesman and got a new one free. Wore out 1 Toro and gave the other to my son when he got a house. Had the Honda for 10yrs now, no problems. I did have a push reel mover once - for about a month!
