Itís quite a well constructed machine, though the castings leave a bit to be desired - usual American pig iron!

Spare time seems to be in short supply at the moment, it's only taken a month to make three head bolts..

The cylinder head seems to sit down nicely, I'm not sure if it will actually need gaskets at all.

I moved on to milling a keyway for the crank gear - the keyway in the 25 tooth gear measures 3.30mm and my closest end mill was 3.00mm. The keyway was milled on the centre line and finished to size with fine needle files.

The governor will be belt driven, the pulley will also act as a retainer for the gear.

The cam wants to sit on the centre line but the casting doesn't allow for that, as can be seen from the previous photograph.

I have marked out roughly the area that will be milled out to accommodate a block that will locate the cam spindle. The idea is to fit the block in place and then bore it to size for the cam spindle. It can then be fitted with a retaining set screw and a "couple of thou" polished off so that it clamps the spindle firmly too.

I'm not worried about loosing material from this area, the casting is seriously substantial for the size of machine!

Last weekend's trip to Oakley provided a couple of parts for this project, one was a cheap but rather neglected trembler coil for the ignition. It will stay in the warm of the house until required, hopefully it can be restored to working order.

Dan Pt very kindly donated a governor to the project, here is my thinking so far..

The governor's pin moves downward as the weights are slung out - perfect for working the slide of a Villiers carburetor. If I can make up a cap that screws on adapting it to fit, it might just work.... tarted up a bit and belt driven, it should look the part!

Looks like a decent plan, just remember to leave a fair size radius in the corner of the cutout to the block.

So as not to invite cracks I suppose, good shout!

Don't you think that carb will spoil the look of the engine? If nothing else it's a bit big.

We know you're a clever bloke, so why not look into making a 'Shepherd Carb' for it? They're not complicated things for an application like this. Look at a Wolseley (obviously!) one for inspiration, and the things found on model Red Wings and the like and I'm sure your creative juices will flow and something more appropriate will be born.

However, as you've said previously, don't try and make everything work at once. Get it running ungoverned with a working carb on a trembler, and then you can play at improving it.

And one other thing - hurry up. I'm getting impatient and want to see it running!

Interesting potential re-purposing of a Norman T300 governor

Does the half time pinion have to sit on the centre line? If there is a meaty enough area lower down on the base, it might be possible to bore, spot face and fit a stepped spindle through.
