I didn’t have any success setting by instructions either, I just kept rotating crank and resetting plate until it was set.
It is the same as mine. The light comes on with supply interruption, ie spark time.

Hi, I fitted one short ago after about half turn of crank to activate the light comes on then goes out and the next time the light comes on continuing the clockwise rotation the 1,4 should line up if correctly adjusted. That’s probably as clear as mud, but mine seems to be running fine. Good luck! Johnny.

CB500/550 / Re: Cb550k3 Rectifier

Thanks very much guys, that rectifier looks very interesting, anybody else tried one? I think at that sort of money you can’t go wrong. Seen a couple on dk spares but everything advertised 39.99 postage and they don’t use Royal Mail which is cheapest for sending to Orkney, especially something that can be slipped into a small Jiffy bag.

CB500/550 / Cb550k3 Rectifier
« on: June 28, 2020, 05:57:45 PM »
Hi everybody, anybody cruising today? Went for a run just about 18miles switched to reserve fuel on my return to town so filled up, pushed starter button wouldn’t even turn over, thank god there’s a kick start lever. I came home checked voltage on battery 11.3 volts! Not good. No power whatsoever getting from alternator to battery. I have a suspect rectifier with a slightly fried red/white wire. Question is replace with just rectifier or replace with regulator rectifier. About the same cost wise from what I’ve seen so far.

That reminds me of a C90 someone delivered to me some time ago, put some petrol in and hooked up a battery and started and ran sweetly. The PO assured me that it hadn’t run for 30 years, took the engine out and dumped the rest. Ironically delivered to the recycling centre, can they recycle rust?

CB750 / Re: RPM hang at idle throttle.
« on: June 22, 2020, 07:03:43 PM »
Hi for what it’s worth I thought that characteristic was something that I was just going to have to live with on my K3. Until I removed carbs for the third time and pulled pilot jets cleaned system thoroughly. It now idles as it should runs smoothly and no longer hangs on to revs. The reason I pulled the carbs was because of the poor starting and rough idle.

CB750 / CB750K3 replacement Seat
« on: June 20, 2020, 08:55:30 AM »
Hi all, Any recommendations for the replacement seats from P&K Classics. I had my 550k3 seat refurbished by them and I was very happy. Just wasn’t sure about the reproduction base etc. Looking for 750K3 seat.

Cheers Bryan, yes I remember these when I stripped the carbs. They were all replaced, the bike is running well but not starting well when cold. I do have resistor plugs fitted at the moment but have another set of non resistor plugs to fit. Also dropping back to correct pilot screw setting might help. Thanks for your help!

Thanks very much! found in Alladins Cave, just as I thought 1 1/2 turns. Yes they don’t make it easy I was beginning to think I had a set of 500 carbs, which I probably do but common to 550 also.

CB500/550 / PD46A setting
« on: June 08, 2020, 10:41:41 PM »
Hi all, can anyone tell me what the base line setting is for the pilot system for my K3 as my Haynes doesn’t even cover these carbs. They are set 2 turns at the minute but I have a feeling they are supposed to be 1 1/2.

CB500/550 / Re: Ongoing PD46 carburettor woes (possibly)
« on: June 03, 2020, 09:29:58 AM »
I have experienced a bit of these woes, as many of the people on here have. I have had my carbs off three times and have found the easiest way for me is to remove air filter box and drop air box collector with intake rubbers attached loosen off 8 m6 nuts from intake manifold pull back and slide out. This is probably not much help but I have juggled between poor or faulty plugs “ngk” and blocked pilots and this was even after an initial complete strip and rebuild of carbs. I remember prior to a complete restoration of my bike I took the carbs off and they were ultrasonically cleaned, made no difference whatsoever probably pilots blocked. Also all four had blocked vents. I now have a bike that runs and ticks over very nicely, in fact I have never had the bike running like this in the 33 years I have owned it. You will get there, (hope it doesn’t take 33 years)! Good luck!.

Small brass interference fit sleeve over it would sort it provided it didn’t interfere with float movement, if you knew somebody with a lathe. Otherwise replace carb body.

Hi Simon, that’s reassuring to know, when I purchased mine I think it was just at the start of re- production as I had waited a number of years to get a set. Thanks for reply!
