Personally I would advise against using “modern” twostroke oil in your type of engine. They were designed to use a straight 30 type oil mix.

Andy.

I was once told (but can’t confirm this) that the piston rings from the Anzani Super Single outboard motor are the same , perhaps a good search online may confirm this.

Andy.

Best way is to measure shaft centre to centre , outside diameter of both pulleys , quote these figures to any reputable belt stockist , and they should supply you with the exact belt.

Let’s hope the poster tells us what plan he has , he appears to have removed the clutch spur in one of the pics. The remaining paint on the gearbox would maybe suggest AutoCulto or Trusty Earthquake , the Jap engine would certainly make an interesting and unusual conversion.

Incase you’re concerned over engine spares , your engine is standard Villiers the carb is a little more obscure , but parts are readily avilable , as are all other engine internals , gaskets etc.

The Mark 25A was used on Auto Cultos , Colebys and some generators ,along with various makes of twoman chainsaws, same bore size to the model you quote , and I believe shared the same piston rings.
I’ve only seen the Mk17A on ex WD water pumps , and a few Auto Cultos.

We must also consider that in our hobby machines with their original factory matchung engine/chassis numbers are few and far between. Users back in the day , would use used parts from donor machines.

Andy.

New parts turn up from time to time on continental E-Bay sites , worth keeping a look out.
On these shores they are next to impossible to find , striking lucky with someone who has had some spares on the shelf for years is your only hope albeit very slim.

Andy.

Wishing all of you a healthy and happy Christmas…….. may all your nuts and bolts undo easily , your magnetos spark , and your fuel flow.

Above all stay safe.

Andy.

I’m at long last using a fuel addative (the Briggs and Stratton one) , early days yet , as my fuel is seldom kept that long , but starting and running issues are non existant…….. expensive , but it seems so far like money well spent.

Andy.

Another great effort from all involved.
Renewed my membership before it came , and have recieved card back…. a HUGE thanks Charlie.

Good day , and a warm welcome to our forum. A truly lovely machine you have there , and it appears to be in full working order.
I have long thought that the continental machines were light years ahead of our offerings , reverse gear , reversable ploughs , and overall build quality, Alot of ours(but not all) were cumbersome , cronic to use with no…[Read more]

If the felt is still intact , simply wash it in petrol , dry it thoroughly and put a couple of drops of engine oil on it , squeaze gently between thumb and forefinger…….job done.

“I agree that the Bingham working days were fun and it’s a shame when these things develop into competitions because the fun aspect tends to get forgotten and the pursuit of prizes is all consuming.”

Absolutely spot on , the very reason that I never have , or will get involved in ploughing events.

Andy.

Only my opinion , but I would NEVER skimp when it comes to magneto components , it’s worth every penny to renew all the components , it will give you effortless starting every time.
Forget about testing with a multimeter , there is a very good reason why purpose built ignition testers were made.

That seems to appear the wrong strength govenor spring.

Andy.

Peter , any chance of a pic of your govenor weight housing assembly.
Can you manually rev the engine and feel the govenor working??

Andy.

Peter , you’ll get there , the various throttle systems on JAPs are all fairly straightforward.

Andy.

Peter , it’s just not noisey enough….. but very nice.
