I suspect Ken is right about the quality of Gerben work look at my 500 carbs!

no worries, I can always save it in case I need it.  It nearly ended up in the scrap but now thinking should keep just in case.

If you want to sell that incomplete set of carbs Florence let me know. I presume they are 627B?

I have the parts to complete them so I might be up for a little project.

Sorry Ken, I imagine they are no good for restoration, the aluminium of the carb bodies at the inlet on two of them has corroded very badly indeed.  I am not sure how, they came like that in a job lot of spares.  Strangely the throttle mechanism is in very good condition, even the chrome part but as I said the carb bodies are scrap.  Luckily the float chambers are good and I have already needed to fit two of them to my bike as every now and again the brass tubes split, probably down to ethanol in the fuel.

Not as good as I thought

Hi Florenece I will PM you - what is the loose metal collar on the shaft  in the second photo?

[florence]

not sure, just part of the setup

[Oddjob]

It's not meant to be on there. It looks like the cap on the lifter arm, the one that covers the felt washer.

I've just assembled Carb:1 the float level was 22 mm as per the manual.
On  taking Carb:2 to bits today I was surprised to find silicone type sealant was used both on the carb top gasket and for the fuel bowl O rings.

Not by me

I know that Bryan the work was done by Gerben, I was surprised that they would use an adhesive when there is no need unless it's belt & braces to avoid returns.

As my Dad used to say a firms reputation is only as good as their worst mechanic.

Good bit is the bowls and top were easy to shine up again. Quite a few of the bowl screws were rusted so I've used SS replacements.

Stranger & stranger all my 500 needle circlip positions are set at the second groove from the bottom - richer than the standard center circlip position 3 out of the 5 grooves.
