I’ve just had similar situation.
On mine the disc was brushing the left fork leg. Worse on left lock freed off on right lock.
Somebody had got the collar at the wrong end of the spindle.
Once I’d freed it off, it had been there for a good while, and put it on the nut end of the spindle, problem solved.

Thank you Trigger, on an *extremely* close inspection this morning I discovered that my spindle was in fact 2 pieces not one. Once I’d freed the collar off and re assembled everything with it at the correct end of the spindle, everything goes back together as it should, with a space between disc and fork leg.
The scary thing is, somebody has been riding the bike like it was, for long enough for that collar to be stuck firmly in place.
The Haynes manual shows a typical assembly, I initially assumed mine wasn’t typical.

According to my Haynes manual the spindle nut is on the left but mines on the right.
Thinking to myself ‘well that’s it’ I went out to the garage and spent an hour coming to the conclusion that it only went together with the nut on the right which is how I’ve inherited it.

Ok so I’ve got round to looking into why my CB550K0 1974 is a bit difficult to move.
Thinking it was just new pads or adjustments I’ve found it was neither.
The disc is just touching the fork leg.
There’s no guarantee it’s the right disc or that it’s on the right way round for the offset to work.
Any pictures, suggestions or advice appreciated.

Thank you Nurse Julie and K2-K6 there’s a few things for me to go at there.
Currently (pun intended) I’m sorting out a wiring ‘situation’ because the new battery went flat.
This made me wonder if combustion was going off because of a weak ignition circuit.
I’ll get back onto carbs tomorrow / the weekend.

I understand why you’d say that. However I can’t imagine it would be possible to make a bendy guitar string go through a hole which was smaller than it.
Anyhow, I’ve replaced the slow idle jets with 38’s and balanced the carbs. It’s much improved but coughs a bit going up the road, lacking power. Once revs are at about 3500 it’s much better. That’d be Main jet though at that stage.
The exhaust still indicates running rich, any attempt to put a filter in the airbox makes that worse.
I’m contemplating dropping the needle to lean that off, currently needles are on the middle setting.
Vacuum gauges are on about 8 inches which if I’ve converted correctly equates to the book 16-24 cm HG

Thank you, I’ve finished the ultrasonic clean today. I gave up and bought one.
During the rebuilding I kept thinking’this doesn’t make sense, it’s running rich, I’m cleaning fuel ways out’.
Anyway I fed a bit of guitar string into the slow jet. This measured 17 thou. From memory that equals .43mm the jet is marked 38 so I think there lies the problem.

Thank you for that Trigger. I have no idea what’s been poked down holes over the last 45 years, this makes it interesting though doesn’t it.

I don’t notice any change as I alter the air screws.
Definitely runs richer set anything less than 3 1/2 turns out. It was on pod filters so no shortage of air.

What would be the consequence of having too much fuel in the float bowl?
Not enough to cause it to overflow but too much?
I’ve set floats at 22mm.

Sorry about this, I’ve gone through various posts and can’t find any answers.
I’ve got 022A carbs on my CB550K0
I’ve stripped them cleaned and replaced the O rings but not jets, just cleaned those. They’re stock 100 and 38
I’ve replaced a dodgy rubber which was leaking
I’ve had gauges to set the vacuum
I’ve static and strobed the timing
I’ve ditched the pod filters and got a used airbox, filter is dirty though
I’ve got it to run but it runs very rich, the air screws are out about 3 1/2 turns!!
Nothing seems to make a jot of difference. Needles have been up and down, currently in the middle.
I’ve read there are fine holes in the carb body which block, I did blat carb cleaner down the ones I could see. Had this problem on another bike which took 3 goes to get them cleared finally using a guitar string.
So any suggestions and how do I get the bloody carbs off now it’s connected to the air box??
