Hi Alan To add to what Adrie has written, the KH and FH inner chain cases are very similar but if you look at the area where the battery carrier is mounted you should see either KH or FH stamped in the casting..the casting is actually the same I think, it is just machined slightly differently...henc...

Good fork springs are part of the solution, Ariel steadily increased the strength of the front fork springs over time so my advice is to use the later type, Roger at Drags can give you the low down on this but the springs are not expensive. I think that the wire diameters, numbers of coils plus free...

I bought a set of MkII square four crankcases from him a good couple of years ago and had no problems.

For crushing the ends to get the flat bit...

Richard I have just noticed that you are in NZ so assume that you will not be dropping in to sunny Berkshire to collect any MkI spark plugs, but it may help to know that Paul 'Grubby' Wiggans in Aukland (Pukekohe perhaps) is currently restoring a MKI so may be able to help with advice. His email is ...

Richard My wife has a 1949 MkI but although she would not know what sort of spark plugs she uses, fortunately I would or at least should know! Having said that, I am not positive about the number but I think it is Champion L86, they are readily available and in fact I buy them by the box of about a ...
