Honda Mower problems

[Tim Stobart Tree Surgery]

Hey all,

 

I recently got a spotless honda mower with a roller on it, just a wee 17" job, from a customer who has had it in her shed for a few years untouched.

 

It's running well, but always on the choke. Dies as soon as it's off of it, apart from a couple of times when it runs as it should. What could be causing this (it's now done 10 or so hours)?

 

Also, is there a way of changing the drive or gearing to make it walk faster, as it is painfully slow to walk behind? I'm sure I could just put a bigger drive cog on or something like that.

 

Cheers, Tim

something stopping the fuel somewhere.

Have you tried upping the revs on the idle screw? That should make it go quicker. Carb may need a clean if it's been sat. It may be junked up from stale fuel

Carb will need removing, strip down and clean for a start.

Any thoughts on the drive gearing? Can it be made to walk quicker? (I know that this will have consequences on how well it cuts and collects).

I reckon it will be a 425C?

They are pretty slow, apart from upping the revs to around 3200 there is not a lot that can be done about the forward speed.

 

And the carb issue is typical of the Honda GC carb which is very intolerant of any contamination (give me a Briggs engine any day!). It will need a strip down, including removal of the main jet and the nozzle above it. An ultra sonic clean is advisable.
