Default JAP Model 3

Hi all,
I have just aquired and cosmetically restored a JAP Model 3 engine. I would like to know what type of spark plug should I use on it and what grade of oil also. I started the engine yesterday for the first time. It starts right away but as when I remove the choke and increase the revs it shuts down. What could be wrong? Does anyone know the points gap?

Is it a Mk3 or a 4/3 engine ?

What sort of magneto does it have and what is the type number of it?

I have books for most of the JAP industrial engines here, but need to pin down exactly which engine you have. Carburettor type would be useful as well, there are three main carbs used.

Hello Peter,
The cover says Model 3 on it. The carb is an Amal type and the engine serial number is; 3F/9252/5. The ignition is points and condenser type under the flywheel. Hope this info is enough as I would be interested in buying any literature you may have regarding this engine.
Thanks.
Glen

OK, I'll have a look through the books.

The flywheel magneto will be a Wipac unit.

Smokey, I have some original JAP literature from many moons ago. I think it is motorcycle related but not sure. Let me know if you are interested and I'll dig it out. I have no use for it and will let it go.
