Your flywheel and crank clearly show that a key should be fitted , get yourself a snug fitting key and you do not have to faff around with the timing as described , it will be spot on with the keyed method , it’s the whole idea of having a key in the first place.

A 16h definately should have a woodruff key.

I’m not convinced that a “ride on mower” transmission is suitable for draught work , many of the standard ride ons had transmission reliability issues just cutting grass.

Bish , therein lies the problem , he’s paid for them. Fortunately my daughter is a solicitor , so shortly I shall be seeking some advice.

Same thing has happened to me , had two really good machines taken from what I thought was a very secure allotment shed. So now keep all my gear at home , shed is a bit crowded now , and to make space matters worse , some clown bought some stuff from me on the auction site absolutely MONTHS ago , and still hasn’t had the decency to pick them up.

Don’t know if it applies , but how long have zenoah been producing machinery.

To avoid pulling your hair out , remove the stator plate , and take the complete ignition to your local garden machinery dealer , they “SHOULD” have a purpose built ignition tester , have it tested and go from there.

Charlie , there is a job lot of NOS Clinton spares going on that auction site , may be of help to you.

Amazing after 40 years it’s not seized , that in itself is one major obstacle that you will not have to overcome.
Look forward to hearing of you progress , Simars are indeed truly brilliant pieces of engineering.

There’s an awful lot of truth in the old saying “99% of fuel problems are electrical”.
The best way to rebuild a Magneto is to source the parts and do it yourself , the only part most of us won’t have access to is a PROPER ignition tester , but generally we know a man who has..
Glad all’s well .

“One of the great things about our hobby is we can use what we collect.”

Exactly , great feeling when you can actually use these machines , all mine have to earn their keep.

Good result Angus.

[andyfrost]

Angus , yes there were both 3 and 4 hole starters for the F12.

Andy.

[andyfrost]

Angus , I’m thinking you require the pressed steel type starter rather that the cast alloy type.
I’m fairly certain it is the same as some of the Villiers lightweights , failing this the cowlings would be interchangeble , and you could revert back to the Siba type starter.

Andy.

I’d hate to tiddle on your bonfire , but from your description , it sounds to me as if you still have a magneto problem.
