Thanks, I'm just going to set them both at the same drop when vertical after ensuring that they both are the correct measurement when done the service manual way.

Some more info required from you kind people please.
I had set the floats to the heights to the measurements specified in the manual and pic in post without much hassle, however when I turned the carbs the right way up I noticed that one set of floats were hanging down a good few mm than the other set, they are ok when on their sides on the bench for measuring but one hangs a bit lower when turned vertical.
I had a good look at the floats and noticed a second tang on each set of floats which came into contact to on of the cast pillars that the float spindle goes through, one was slightly more bent on one set of floats than the other causing the float to hang down further when the carbs are vertical.
Obviously, both should hang down the same, but one set of floats is lower due to the bend in one of the tangs hitting the pillar first, is there a distance they should be set to or is it just a case allowing a bit of free movement?, as I mentioned when measured on their sides they are spot on.
Don't you just love 50 year old bikes that have gone through a few pairs of hands!
Thanks

Thanks for that, on thinking about it when it shuts off the fuel seems logical as there will be wear on the needle and/or the seat after a while in use.
I have a remote reservoir so will give it a go.
Any thoughts on using a S/S dowel as a float pin?

After being unable to get to work on the bike for a wee while I have managed to get back to it. Before measuring the float heights I noticed one of the float was not moving as freely as the other so I removed the pin and noticed it was slightly bent with a couple of gouges on it. I tried the float with the other pin inserted and it bounces about no problem. I understand pins are not available on their own, but I am able to get stainless steel dowels the correct length and dia. 28x2.5mm, would they suffice? I notice other carbs use stainless float pivot pins so I hope they would. One set of floats was wildly out at 26mm the other 23mm which had me doubting I had measured them at the correct place, the highest point of the float as indicated by the arrow in the picture, could someone please let me know if I am measuring them at the correct part of the float? Thanks.

Thanks for that clear picture, some info I had read showed the carb slightly titled back allowing the tang just to kiss the float needle, going by that picture and instructions the carb is vertical.

Thank you for info, much appreciated.
As from Craizeehair,
I have the FSM from Bryan, I’ve had trouble gaining access to the site so have only just seen this. I am away at the moment but will check as soon as I am back home.
I too have been having difficulty gaining access to the site.

I got a 1976 CB250, (UK G5), model, in nice condition which the previous owner left for over a year but didn't bother draining the tank or the carbs before laying it up. It did start but would only run on the left cylinder, the right plug was bone dry indicating to me that the carb was bunged up.
I cleaned the tank and had it lined, cleaned both carbs to within an inch of their lives, refitted them and both cyls fired, pleased with that but noticed when revved it would hang off idle before slowly settling back down. As there were a few things I wasn't happy with I decided to go through the bike, starting at cam chain adjustment then valve gaps, points and timing, the auto advance unit was filthy so that was stripped, cleaned, and lubricated, everything put back together and the hanging revs problem was gone, good chance it was the auto advance unit sticking a bit.
I realised the only thing I hadn't done was the float heights and the question is with regards to the float height, I have searched for a definitive answer and read info in various places and there seems to be differing opinions on float height and how the carbs should be sitting whilst checking the height, FSM says 18.5mm, carbs vertical with tang just touching float needle and choke side at the top, others give a range of heights from 19mm-23mm with the carb slightly tilted, others stating because of the newer fuels E10 etc heights should be increased slightly.
I would be grateful if someone could tell me which would be the best setting and way to do it please?
Thanks

PS thats not rust, its patina.
You lucky man, 'Patina' can add hundreds to the value of a bike!

£465 is three times what I paid on my Triumph Trident 660 (£151), and I have no voluntary excess.
Agreed, £465 is totally ridiculous, who are you with for your Triumph?

Now, I am sure you are all aware of the the "voluntary excess" type, let's say, 'money making exercise', that goes on when trying to insure a bike.
I have just recently bought a modern bike, a 2017 BMW F800r, having a classics policy with RH I will just add it to that at a not too unreasonable price, but I thought I would shop around to see prices elsewhere. Nine times out of ten when you look at the quote it has added some sort of varying scale of voluntary excess, as I always take no voluntary excess when getting a quote for my car or bike, I take it off and the price may just rise by a few pounds.
Yesterday I got a quote from BeMoto for £465 for a single bike which was bad enough, and with a total excess of £500, made up of £300 compulsory and £200 voluntary, when informed I did not want the voluntary, the young lady sounded a bit shocked and said she would have to go and speak to someone, she then came back and asked me to confirm I did not want voluntary excess, I confirmed and she then said ok, 'without voluntary the price is now £465!', the exact same as with the £200 voluntary, I asked her why it was the same and she couldn't explain it, granted it is not the young lady's fault but it's totally ridiculous.
If I had been inexperienced, or not savvy enough to not want voluntary excess, should I have had an accident I would have ended up £200 out of pocket for taking the £200 voluntary excess for absolutely no benefit to me in reduction of premium at all.
By all means if you have a low excess of say £50 or £100 and you think bringing it up to maybe £250 is fine and you're getting a good bit off your premium, do it, but check how much you are going to pay extra by not taking voluntary excess, possibly just a couple of quid, or in my case, absolutely zero.

What's a sympathetic restoration?

I believe it's where you play classical music in the background whilst restoring it and keep telling the bike, "Now, now, it'll be fine in the end!" I, of course, could be wrong!

I too was with Peter James, but for some reason the premiums hiked up, I spoke to RH insurance and they will cover both classic and modern, like a lot of classic policies there is no NCB but the premiums tend to be more realistic. Not only that you get to talk to a human type person and the is no charge for amendments, which some companies charge up to £50 just to type in something different, another money making con, excess is £50, and you can retain salvage should you have the unfortunate luck to have an accident. https://www.rhspecialistinsurance.co.uk/

Plain or flat, same thing. How tight, well nipped it is how I'd describe it, the split pin will stop it coming off if it's too loose so not so tight that you risk stripping it and not so loose you can remove it with fingers. The step on the bolts prevents you overtightening these nuts.
Thank you!, I just realised it was typed flat instead of spring, nipped up is sensible, thanks once again.
