Did you remove a retainer from the wheel itself, or from the separate sprocket carrier. Racking my brain here, and only recall 1 retainer on the wheel itself, plus a second larger one on the sprocket carrier.

Morning.I have been hanging round this site a lot of late, and I think that I have learned; if Trigger says buy something you should buy it !!But I still recommend you watch: hackaweek "73 honda CB750 cafe racer rebuild " on Youtube. R
There are loads of people on here (myself included) who have used the Cruzinimage kits as in Trigger's link and they are fine.As Rob says, if Trigger recommends something you will be OK!
Personally, the only aftermarket carb kits I will use are from Yamiya or kits like Gerben in Holland sells.. Don't get me wrong there could be nothing wrong with other carb kits but they also sell inlet rubber kits and camchain rubber idlers that I know to be inferior to OEM and causing people on the US site horrendous problems. Gerben has the right idea ..he sells the 'O' ring kits sourced in Viton. He's got a really good reputation for rebuilding carbs. Rubber compounding is a science in itself. I worked for a company for 20 years that were experts in it, so I feel qualified to comment. DS will not tell me who he sources his aftermarket rubber parts from or give tech specs to check for myself, so again I have voted with my feet on that one.http://www.ebay.co.uk/itm/CB500-CB550-4-Four-Keihin-carb-O-ring-set-VITON-rubber-for-4-carbs-/112047503140?hash=item1a168d3724:m:ms0_u4ZL-QLjaYiVzIQED2wDunno if he does kits for 750 (Attachment Link)
The first picture is for CB750 K0 to K2, you need the arm in the second picture to fit the later forks
Did the float valves look ok?, did the little spring loaded pins in the float valves spring in and out?, did you check the float heights?, I found a good "how to" online for PD carbs which mine has, try googling for one for your earlier type carbs, next time you replace the carbs heat the rubbers up (carefully) with an electric hot air gun, they harden with age and are a pig to get on if not softened, the trouble is that because you don't know what previous owners have done it's going to be a bit trial and error, it's got to be a float related issue, here's another thought, do your floats float, they could be punctured and filling up with fuel, that stops them floating up as the bowl fills and stops them pressing on float valve via the arm to cut the fuel off.
