Help with Stuart Turner 1/2 hp open crank gas engine

[Rob D]

Hi all can anyone help?

Trying to get a Stuart 1/2hp gas engine back into life.

I am missing some parts of the carburettor please see the pic attached.
Am also looking for advice in the ignition system as I have an insulated gear on the exhaust cam that has a point that coincides with the ignition point in the cycle. I guess this has to have a set of points that complete a circuit to form the ignition.

Currently the two parts I have of the carburettor are held with a temporary steel plate. Not sure what the missing piece is supposed to look like or do. is it just to transfer gas to the inlet valve? Should the air mix valve be vertical as I have it or horizontal?

Link to the photo below.

Does anyone have drawings? I am led to believe these were sold as kits of castings so there must have been a published design at some stage.

I am able to cast small parts so can remake whats missing if I knew what it looked like.

Failing drawings would someone be prepared to do some detailed Photos of these areas of another engine?

This model of engine seem to be rare and the information on these engines seem a rare as hens teeth.

Thanks all for any help people can give me.

Rob
