Re: steering damper knob

Thanks for doing the legwork Simon. Brian has it correct. Reference to drawing D10/141 shows the damper knob with ARIEL across the centre and a note in the title box "1938 M/cs". So we can be as certain as is possible with Ariels that the damper knob with ARIEL at the top was used up to th...

Re: 1938 square four tank stripe

Ralph, The attached drawing gives you the lining thicknesses and spacing. The handwriting for these is mine and the information came from an original tank which I measured very carefully. I have subsequently seen other original tanks which all match the details on this drawing, subject of course to ...

Re: steering damper knob

The serrations were used pre-war as well as post-war. To the best of my knowledge, this is a pre-war part, the post war ones having ARIEL across the centre rather than across the top. Quite when the change took place I can't be certain.

Re: Front fork oil leak.

I think you may find that the new stanchions are the problem. I have exactly the same issue on my 1954 KH(A) and have replaced the seals several times. It has recently been suggested to me that the answer is to take the stanchions out and polish them over the length that the oil seals bear upon, so ...

Re: 4G Carb / Dynamo Clearance

All the bi-starter type Ariel Solex carbs have the main jet holder with the chamfer so it must have been needed to clear the dynamo before we started skimming heads, rocker box surfaces and rocker boxes themselves. As a rule, there is a bit of surplus "meat" on the main jet holder so turni...

Re: 1948 Iron 4G Coil Ignition

Chris, I am delighted at your progress. The problem always did sound like fuel starvation. Solex adjustments are not too easy or too obvious. Jens Beusse and Otto Mederle, both from Germany, are the serious experts on these carbs. Apart from anything else, they know which parts should be fitted - an...

Re: 4G exhaust manifolds

The thin wall one looks correct to me. I wonder if the thick wall one has been cast using the pattern for the alloy versions of these manifolds, as used in 1948. I doubt it will make much difference, unless you go racing.
