Hi Villiers,
What is the bit that is stuck out at the front on the power drive?
 
It doesn't look in good condition whatever it is.
 
If you do remove it you should make a round plate to fit where it came from to keep the dust/dirt out.

If those are the photo's of your machine on this thread, there doesn't seen to be an air filter fitted, without the air filter it will make the mixture very very weak, and can cause the back-firing, because with the filter fitted it causes a vacuum effect on the carburettor to draw more fuel, the jet sizes compensate for this suction, being smaller.

 

If you are going to use this at all you must find an air filter otherwise you will ruin the engine by sucking dirt into the engine.

 

 Cheers Rob & Kish.


Excellent advice ,Rob.

I took off the air filter to access the plug when I had spark issues . It only has oil in it and a metal mesh affair inside, no paper like modern filters, so I didn't think it would make much resistance with the air flow. But will re assemble, and try it now the spark strong again.

as for the knobbly bit on the front. I thought this was part of the machine Will whip it off and see whats behind.

Right, off for me last 12 hour night shift

Many thanks again

The gearbox originally would have had Castrol XXL in the gearbox and the tiller.

Also you said in the gearbox and tiller?

Where would I fill the tiller? Ive took the nut off between the wheels, but didnt look for anywhere else to fill. Will both be filled from the same sump or is there another fill hole I should be looking for?

Thanks again

Hi Villiers, The filler plug for the tiller is on top ofthe tiller just in front of the rotavator hood and should be filled to just 1/2" below the plug hole, the gearbox filler plug is on top of the gearbox and it's level plug is at the front of the box underneath the engine.

Hi Rob,

Its an education to say the least
Went to pull her out the other day and just shut the door of the shed after seeing this.........



Not a drop of oil when I was turning her over for half a day, then she dumps half the sump on me shed floor


The good news is she ran for a good ten minutes...then stopped....totally. Im reasoning the gearbox got warm ,then this opened up a seal leak

So, it must be the seals......somewhere?

What can I do to find out what seals have failed? There's no indication of where the leak came from ( as shes a bit greasy )

Can I buy new crank seals? or do you have to make them up?

Thanks for the follow up too, Rob

All the best

the oil wont be out the sump as it hasnt got one, if ran ok for 10 mins and then stopped i'm guessing the coil is breaking down when hot. The oil is either out the gearbox or from the fuel leaking.
If it isnt orange it isnt a rotavator

Its definitely out of the gearbox, too thick to be fuel. Dont understand why it took so long to leak out? Like I said, I turned it for half a day,not a drop leaked.

So if it uses the gearbox compression to pull fuel through wouldn't that affect the performance if there's a leak? It ran from cold and not very smoothly.

PS you had a look at the series one on Fleabay....£0.99p start?

i think one of us must be talking at cross purposes here. The engine uses the crankcase compression  to suck the fuel not the gearbox, my own experience of these engines is that once theyve started unless the coil breaksdown or some other part of the ignition system,  they tend to stay running, but are piggs to start when hot, Have you tried a new spark plug?

Hi Series one

Yes I was on about the crank case(thought that was where the gearing was )
I have put a new spark plug on ,also replaced the HT lead. Compression is good and the spark is strong. I thought the leak might stop the fuel being pulled through? Or is it more likely the coil? The reason I ask ,is it ran for a bit. Assuming the coil has done its job (getting the spark through), would it more likely be a fuel starvation problem?

All the best

Hi
Have you got a multimeter as it is easy to test the coil

under compression a spark can vanish, if it ran for a while then stopped its quite likely to be ignition releated. do you know any one with a coil tester near you?

Turn the dial to the 20k Ω setting and put one lead to the core of the HT lead (not in the plug cap) and the other lead to a clean bare bit of metal , preferably just behind the flywheel, the reading should be about 4000-6000 ohms.
Is it a digital multimeter?

be careful with a multimeter as the current off it can jump small breaks in the windings i'd try and find someone with a coil tester, i know someone in blackwood.

for something like that if you take the coil off i often find most places will do it for a drink, - worth a try.

hello. just been following your problems. if there is a yellow villiers sticker on your coil this could be original and 99 per cent of time will be on its way out and could be 70 years old and only working on primary coil. you can get a new one for 40quid from villiers parts cheers.

To find out where the oil is coming from firstly check the gearbox sump nut, Then take a wheel off to check the drive shaft oil seal, Repeat on the other side, ( use a small jack )

Did you unbolt and take off the front implement mount? If you did, Did you seal up the PTO port?, Also check around the area where the engine drive shaft enters the gearbox.
Kind regards,  Jim.

Hi , I think I have a filter for your rotavator, a Villiers air filter like the one in the picture.
If you can contact me I can email you a picture, my email is levtek@iinet.net.au

Thanks guys, Im ashamed to say I havnt done a tap on it since last year.
I got a bit overwhelmed at the enormity of the task at hand. Notwithstanding, I have it on my list for next week. Im off work at the moment, very ill, but could do with a bit of tinkery in the week. So, instant gasket at hand, Im going to strip and sort it!

Hi fellas

Right I've stripped it down

The coil is original, so I took a look on fleabay for a replacementband the coils on there are old,will I have to replace old with old,or is there a new type that fits?
Also,am I right in saying the flywheel isn't bolted on rather its on a splayed shaft which might need a flywheel remover?

I've found where the oil is leaking from too (very productive afternoon)its coming from the seals around the axles. Where would I start to look for seals to suit, or could I bodge something together to get it up and running?
Thanks for all previous advice and any shared anticipated wisdom.

Never ever buy an old coil, there should be two types of new one listed on there, one of which should fit
