Well,here goes,the first engine that Power Specialist used was villiers,A Bux is a villiers under license to Power Specialists, in the first couple of years,then part of the licensing fell away,so that the latter ones,had different parts attached.
A nowadays term for these engines could be classed as badge engineered
You mention Ransomes,They have a long history of badge engineering.
The first engine which was badged was the Simms way back in 1905,this became the Orwell (derived from the river that runs through Ipswich.)
I suspect the engine you are talking about is the Ransomes 4 stroke which appeared on the Mk 10 Motor Mower or on the MG Tractors.This engine was originally a Sturmy Archer,then a license was bought by Ransomes.
Ransomes also badge engineered binks carburettors.
To give another licensing exercise
Atco
Chas H Pugh made under license,Senspray carbs, and also Claudel Hobsen carbs
Hope this clears your head
Kind regards

That worked a treat, thank you. All back togeather and have had it running, however it will now not run without the excess fuel engaged, every time I try to reduce revs to an idle and the excess fuel clicks out the engine dies. Any ideas?

Thanks a lot guys, all great advice, i’ll try this all and will keep you updated…..with good or bad news!
Thanks

Oh and trusty2020 I forgot to say, the ultrasonic cleaning was not foolproof as you said, soft fuse wire was needed to clear a blockage. Thanks again.

Hello again, thought I’d give you an update. I have the Gem back from the mechanics now. He had done a great job, it fired up first turn from cold, then we let it settle down (had to adjust the carb again) and tested it out in a nearby field, what a beast of a rotavator!

He did warn me that he was still not happy with the mixture, it’s either good at idle or good under load, there’s no real sweet spot that I can leave it at, so I should expect to have to play around with the mixture a bit whenever I use it to get the most out of it. Not ideal.

So I got it home and gave it a go again.
It wasn’t running so smoothly this time. I set the mixture so it ran a smoothly s possible and started turning over some ground and it started hunting and nearly stalling
, the choke was opening and closing on it’s own while this was happening, then it started backfiring quite badly and died on me.
It’s stuck in a field now and won’t start at all….it’s a very expensive gren ornament if I can’t get it started, the Joy’s of old machinery!!

Any further ideas?

Thanks

Brett.

Hi Charlie, thanks very much for that. Here’s my email (I’m not a paid up club member so can’t pm you):

richard_wheat@hotmail.com

Thanks again

[vhgmcbuddy]

Oh, I forgot!

Thirdly, has anyone got any manuals for either the scythe or the engine (Villiers Mk12) or both?

Thanks again

[vhgmcbuddy]

Almost finished!

[vhgmcbuddy]

Thanks for the reply, I have done this and the governor is out and the link rod is out, how ever the rack is stuck completely to the right and pump is seized aswell hence why rack can’t be moved?

Many thanks
Josh

Hi All,
Thank you so much for all your replies, i really appreciate them.
Yes, the mag was properly tested once stripped, i had already put in new points and condenser and they have now also bench tested the coil. The spark is now ‘superb’.

These points on the carb airways are where are kind of getting stuck at i suspect, the carb has been ultrasonically cleaned already, it’s coming off the machine again though to double check these airways as there seems to be a theme with these carbs.
I’ll let you guys know how we get on once it goes back on he machine.

Thanks for your informative help so far.

Brett

Thanks Andy. Yes agreed, I have already sent it to a local light engineering company who specialise in refurbing old machinery similar to this. They have stripped the magneto and set the timing etc to make sure I hadn’t made a mistake, so they are suggesting I find an alternative carb.

Hi next stage of fitting plough to tractor doing a wee bit at a time as I hope I am going to do it once how often have we said this
