sandspider Posted April 28, 2023 Report Share Posted April 28, 2023 Hi folks As above. I have an ancient Honda self propelled mower. It works well, but the adjustment slider for ground speed doesn't change anything, one speed only. Engine speed / choke control works, as do the bars for engaging blades and drive. I've had a look at the wire coming off the ground speed control lever, but it gets mixed up with the wire to the lever than engages the drive, so I can't see what (if anything) is wrong. There's a kind of yoke thing that the speed control lever moves, and this just slides along the drive engagement wire - I wonder if this yoke shouldn't slide? (I don't have access to the mower at the moment, so can't take pics and have to rely on my dubious memory!) It's not the end of the world to use it as it is, but it there's a simple fix to give me back ground speed control that would be useful? Thanks.

sandspider Posted April 28, 2023 Author Report Share Posted April 28, 2023 But I can't see a way to adjust the yoke-thing! Will try and take a pic or two this weekend to make it clearer... Quote Link to comment Share on other sites More sharing options...
tiny tim Posted April 28, 2023 Report Share Posted April 28, 2023 Take a pic. Post it and we can work it out Quote Link to comment Share on other sites More sharing options...
sandspider Posted April 29, 2023 Author Report Share Posted April 29, 2023 Cheers, pic attached. So, the bit with the split pin moves back and forth along the U shaped orange plastic thing as the speed lever is moved. But when the drive is engaged, the split pin moves freely with the large spring at the left. It seems that adjusting the speed lever might just move the split pin up and down a bit, vertically on the pic, but this doesn't make the ground speed change...

tiny tim Posted April 29, 2023 Report Share Posted April 29, 2023 At the other end of the cable. Is it loose or needs adjusting Quote Link to comment Share on other sites More sharing options...
sandspider Posted April 30, 2023 Author Report Share Posted April 30, 2023 Other end of the cable seems ok as far as I can tell. Adjusting the orange lever doesn't do much, but engaging the drive tightens the cable and off the mower goes, one speed only. Quote Link to comment Share on other sites More sharing options...

tiny tim Posted April 30, 2023 Report Share Posted April 30, 2023 Page 28. We used to put the spring in the other hole on the governor or bend the spring to increase the revs Quote Link to comment Share on other sites More sharing options...
sandspider Posted April 30, 2023 Author Report Share Posted April 30, 2023 Cheers. I'll dismantle that bit and see what's going on when the kids go back to school! Quote Link to comment Share on other sites More sharing options...
