Well, air corrector jets are usually refered to as say 0.5.  Pilot jets are #25 or #30 for instance.  Is that what you meant?

and they seem to be 0.5 for both 360 & 361 carbs, meaning the third note is really not applicable.

OK, think that is sorted........... what about the rest now?

I can do this in A3 to go on one sheet but most people do not have an A3 printer.

Latest version:

Latest version:

Stephen- just checking this is the very latest one?

I am going to strip my 350 carbs this week to see what is inside them before going any further with my resto so would just like to check.

Many thanks for all the hard work on this.  8)

Latest version.............. On 2x A4's.

There are still gaps in it so need more help to fill it in as I have exhausted my own knowledge and available data that I can find. Someone mentioned the Cycleserve manual, but I have not been able to track this down.

Haven't got the Clymer manual either....

Yes, 350's 1 3/4 on the unbaffled filter versions, 1 1/4 on the baffled B only.

I had come across the R5C "variant" but had no confirmation if it was so and if it was US, EU or UK....?

As for missing stuff, easier to look at the PDF instead of me putting it all up here, the missing info is left blank.

Yes, I came across info that the A could come with 3 versions of carb setup.
Most common is the black low-top, un-baffled, 2.5 slide.
Very late A's had Hi-tops that normally would have a baffled filter but as you know, UK data is virtually non-existant, even though we know these setups existed.
So, what I have done is put in the 3 possible setups that an A can run with:
1: low-top un-baffled.
2: low-top baffled.
3: hi-top baffled.
The hi-top did not come standard with an un-baffled filter, always baffled, so anyone with 140 main in a 350A, fittted with a hi-top has had it changed by someone.
None of the A's had the airbox tube correction to my knowledge but that did not effect the jetting across the baffled filter versions.
360/1 is a part code correct, another one slipped through the net, that's why I keep putting this up for scrutiny.
That should be 351/2.
I was contacted by a member that they had a R5C with the same settings as a R5B so I am confused as to what goes in there and there is the possibility that there is a country version here.? Will have to go through all my messages to find out where that came from........  ::)

Thanks Stephen, and also everyone else who contributed to this- looks like a minefield.
