Re: Oil tank

Get as much muck out of it as possible (flush/rattle/flush with petrol+old nut+bolts or similar), fill with a proper rust remover (I'd probably use a molasses solution, others swear by white vinegar - or maybe the stuff that Bilt-Hamber sell), leave to stand for a long time then clean out, check and...

Eddy:
I think there's a limit to the pictures that can be attached to a single post, if you want to put more up just attach to new post(s).

Re: VB Carb float chamber leak

If that new green washer is made of the same stuff as the green ones supplied with my new concentrics I'd look out for more petrol leaks in time - over a month or two mine slowly but surely dissolved in modern UK petrol.
Be on guard for green stains around the bottom of the jet block.....

Re: WNG Bad Engine shock absorber sprocket

...The strong spring is the answer as coil binding or the bottoming of the back face of the cam will be a sudden stop which will damage something by the way it hammers.

Re: WNG Bad Engine shock absorber sprocket

Luis: I think the spring was used on all singles from 1930. The sprocket and sliding member changed for 1941 - W/NG can have either type, the difference is the width of the cam face. (I'm just reading from the '41 parts book here!) Early sliding member sprocket 1 3/8" OD over cam, later is 1 17...

Luis It's not supposed to be able to rotate through 360 (in my experience, if it can it'll be like a weak clutch, it'll slip completely under load). It just needs to be able to 'give' to act more like a cush-drive. (I think in practice they are stopped from rotating completely either by the spring b...
