Carbs rebuilt and new coils and caps installed. I've ordered a thin walledI18mm socket to get plugs 2 and 3 out. Just need to find a fuse box as mine is missing.

Is anyone able to tell me the difference between these needle jets. The ones in the carbs that came with the bike have 2 smaller holes at the top end and an extra singe hole on the side. The one that came in the replacement carb Mick sent me has 5 holes the same size and no single hole..
Edit..
I read on the sister site that Hondaman suggested drilling out the holes in the emulsion tubes to make them bigger. I could drill the 2 smaller holes to match the others then drill a single hole in the side of the other jet.
Playing with fire I guess and there would be no knowing what effect it would have until I could actually ride it... That said miss matching ones would probably be worse?

was there one in the spare carb i sent you? i can find you one if you are stuck.
There was yes, that one came out easy. One was missing from the original carbs and 2 others unfortunately got damaged when I was trying to get them out because they were so corroded in there. That would be great Mick. I'll send you a PM.

The odd thing about your pic is that the float bowls don't match the carb. The one on the left does as it's drain screw faces the right direction (they face out not in so you can get to them) the one on the right is a float bowl from either 3 or 4 cylinder.
Well Spotted! I just took a pic to show what they looked like before and after the ultrasonic clean and polish, it isn't a matching bowl with that carb

You can tell which is which by the positions of stuff like the mixture screws etc for example, if the mixture screw opening is on the right it's either 3 or 4 cylinder, left and 1 or 2 cylinder, after that you can tell which is which by the way certain stuff aligns, stuff like the blanking plugs fitted where the slide pivot pins are fitted. Study them before dismantling and you'll start to spot the differences.
As an example, your pics show 2 internal carbs as those have the vent pipe fittings, the one of the left is number 2 cylinder as it doesn't show the mixture screw opening and the blanking plug is showing. The one on the right is clearly the broken one that you replaced as it shows all the same fittings in all the same places
Ok got it, Thanks Oddjob, I've got lots of photos but I'll make notes of which side the blanking plates, mixture screw opening, slide pivot is etc too.

I haven't had chance to see the bike for a while and only had time in the evenings so I've been sticking to working on the carbs.
They are cleaning up quite nicely and thanks to @Mickwinf I have a replacement no. 2 carb.
Before and after
Quick/stupid question, If I wanted to get these vapor blasted, I'd be removing all the throttle/butterfly shafts which help identify which carb body it is. Is there a way to ID each carb (1-4)? I can't see any markings on them apart from A-2 inside the float chamber.

ok this is a number 2 carb, looks to be in sound condition. Yours for a donation to the site
Thats brilliant Mick! Thanks so much. I will send you a PM. In other news.. I managed to get the stuck float pin out with the help of an auto punch. it freed up the pin in the towers but was still well and truly suck in the float so I had to cut the float and pin with a dremel, but its out! Are the aftermarket floats and pins from DSS any good? I don't really want to pay £50 for an OEM one.

i have a set with one carb worse than yours, i think on mine it was the end one but cant remember which one, will check and let you know. they are numbered from the left side of bike as you sit on it, the carb with the choke control is number 1.
Thanks Mick! ok its its number 2 with the corroded jet post then, if you have a spare housing your willing to sell that would be great! Hopefully I'll get the pin out of Carb 4 and that won't need replacing... Best tip I can give you is buy a decent set of JIS screwdrivers, all the cross headed screws which are JIS will have a small punch mark on the head, JIS screwdrivers are a perfect fit for these screws and you risk rounding them off with a normal Phillips screwdriver.
Decent set for a decent price here.

Thanks Oddjob, Bought a set of Vessel JIS screwdrivers for my last project.. eye-wateringly expensive but saved me on a few occasions.

Good to see another 550. I have the same model and colour. Mine was a US import 3 years ago and in much better condition. It showed 32k miles and all looked pretty straight and don't think the engine had been apart. I thought about getting it started, but after draining the oil and removing the sump the primary chain was chewing away at the cases so I decided not to bother and to completely strip. Only surprise was the upper rear engine bolt which took a week to remove. Managed to get a reasonable condition original silencer on ebay locally for a fiver! All back together now.
Nice work bike looks great!

use some heat on the post pins and be very careful. I have some carb bodies if you need one if i have the correct one, what number carb is it?
Ok I'll give some heat a go. The one with the deterioration is the third one in from the left of the bike. The one with the stuck pin is the first one on the left. Not sure how the numbering order goes

Got the carbs apart. 3 of the float pins came out ok.. one is stuck in there. Rather than break the post I've seen on another thread that a decent automatic centre punch can work so i've ordered one.
Another issue is one of the needle jet (main jet)? housings has badly deteriorated, looks like I might need to find another carb.

Make sure the negative lead of the battery has a very clean connection to earth.
Mine didn't so the current went down the small earth wire in the main loom and melted it.
Ouch! ok I'll be getting the dremel wire brush attachments out then.
