Honda Izy drive speed adjustment

[Jonny5]

Hi all,

 

Thanks for your help this far. I've got a new query about my mower. I'm cutting large areas of grass and the forward drive is tediously slow. I'm not sure if I'm imagining it or if it has got slower over the past year. Is there a way of adjusting the drive speed? I presume the drive is linked directly to the engine speed, so is there a way of increasing engine rpm, without damaging anything?

 

Many thanks, Jon-Paul

Friend of mine had the same problem with an Izy, so he bent the Governor spring a little. Or you could put a bigger pulley on the engine.

Hi Tractorboy. I've been looking on the web for an engine diagram or manual but haven't found one yet. I know roughly what does what on the engine but not sure of the names of components. I've moved a spring onto the second hole (to the right). Doesn't seem to have had any noticeable effect. Is this the governor?

 

Thanks

Think thats what it is called, try pulling in with some pliers with the engine running see if it speeds up.

Hi, It does speed up yes. Even when I moved the spring onto the next notch the run speed didn't increase though. Any ideas?

 

Thanks

How would the pulley idea work? Is it something I could do myself?

You could do I got a larger pulley off ebay for my mountfield, and to drill it out to fit the shaft. Then got a sightly longer belt from halfords.

If its a fixed drive speed then you need to increase engine speed by adjusting the idle screw I think, we have done this before on an Etesia which was sluggish and it worked to a certain extent.
