You have the TO20 with Continental Z-120 (120 cubic inch) engine which was made in the US. The Standard engine was made over here in the UK by a different manufacturer (Standard Motor Company).

The spot of weld on the rocker arms may have been to build them up again after a lot of wear - I have done this on mine with a MIG welder - the top end had suffered badly after years of neglect.
I hope you can still adjust your tappet clearances . . . . . .

Outer rims, for the sake of neatness, the bolts face inwards (nuts and washers hidden from road) with the wheels on normally (centre dish convex to road).

The wheel dish bolts are fitted with the little nib located into the wheel dish itself, to stop it turning and of course the dish can be fitted a number of different ways depending on the wheel settings you use. It is possible to fit the wheel bolt with the nib into the bracket on the wheel rim but there is a chance that it will start to turn as the locating is not as secure as the other way especially if you have to remove it after its rusted up.

Hi Larry

Not wierd, no, there are other TEs over your side of the pond. Yes the Continental engine was factory fitted. I don't know about the drip holes - never taken a Continental engine to bits - but the Standard engine had drip holes, so I guess the same for Continental, too, it all helps the oil get around for top end lubrication.

After 25 years in the shed, some fresh gas, and a quick charge on the battery, and she will probably fire right up :)

Did you mean that the drip holes on the top of the rockers have been welded closed?

If so, that's not what I did to mine,as I had to build up the valve (tappet) end of the rockers. Blocking up the oil holes may have been an attempt to improve oil pressure/lubrication.

Yes Jim, fresh gas and jumper cables and i know it would have started. But i want to restore it so i didn't even try. If i get my kid to download the camera i'll post pictures, got it striped to the cases. According to the local repair man, filling the holes was done to force the oil out under the rocker for better lubercation
