Title: PD46A setting
Post by: Johnny4428 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.

Cant remember offhand but the 77K3 supplement to the 500 manual is mostly about the carbs so should be in there

Alladins cave on here, Ash put all my manuals in his dropbox Note ! It is a supplement to the 500 manual so you have to look at that

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.

If they came from UK they wont be 500 carbs, the 500 K3 never came to UK.
If you remove those screws there is a spring, a washer and a tiny O ring on there All are necessary

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!
