Re: BA kickstart quadrant stop rubber advice

I've ordered some nylon suspension bushes and will see if they can be fitted inside the old metal cap. I wouldn't expect the nylon to deteriorate in gearbox grease for a year or two. bushes 1a.jpg Possibly a job for that new-fangled 3D printing.... Does anybody have access to a 3D printer I can thin...

Re: BA kickstart quadrant stop rubber advice

So they have specified the wrong elastomer. How about looking for a suitable bit of viton tube?


Simon, Is there a particular grade of Viton I should be looking for?

Re: BA kickstart quadrant stop rubber advice

Did it have the metal ring around it, like a small Silentbloc bush? Simon, Yes it had the metal ring however, when first fitted, the one from Drags looked like it had been a smaller inside diameter and been roughly drilled out. The rubber inside the bush has now broken down to to a slimy black mush...

BA kickstart quadrant stop rubber advice

I rebuilt my BA box 2 years ago and replaced the kickstart quadrant stop rubber (3338-33). I have just had the outer cover off and find that the rubber stop has completely disintegrated. I am surprised that it should fail so quickly especially since the gearbox has done less that 1000 miles since th...

Nuts for Watsonian Sidecars

Does anybody know where I can source some 3/4" x 20 tpi nuts for a 1950's Watsonian sidecar? I assume they are either BSCy or UNEF. Zinc plated would be fine but ideally I would like Nyloc or similar for the wheel axle nuts.

Re: solex - poor mpg

Simon

I think that there were 2 originally which is what I have now.

Interestingly new float valves for VW Beetles, which are a similar carburettor, come with 3 different thickness washers.

Re: Solex - poor mpg

Mark, When I first ran my 4G after reassembly the fuel consumption was very poor and it was obviously running way too rich. It also had a tendency to dribble fuel if the machine was tipped to one side even slightly. Originally when I had stripped and cleaned the Solex carb it had multiple fibre wash...

1939 4G toolbox

I have bought a toolbox (of unknown origin) which I am aiming to use for a 39 Anstey 4G that didn't come with one. Pictures of 39 4G's on the interweb seem to have a huge variety of different toolboxes fitted - some of which are similar to the one I bought. Does anybody know of a definitive drawing/...
