Thank Bryenj. Yes, I took the jets out before they went to USC & will sort them out individually.

Great 1st experience. Thanks for everyone's help.

I decided to get my PD46A carbs vapour blasted which meant the daunting task of stripping them down but I used the excellent guide that Brian Louis Barnes has in the SOHC files, took tons of photos (especially that pesky spring arrangement between Carbs 2&3) and it went well. If I can give a tip it's to replace ALL cross-headed screws with allen cap bolts especially the ones that hold the lifting mechanism onto the slide of each carb.
CB550K3, CB550K1, Yamaha Midnight Star, and CA77 in 2473 pieces (at the last count)

Yes, I read elsewhere in the forums that these pesky carbs can be prone to "going off" when stood. That's frustrating (particularly when the bike will no doubt be used on the rare sunny days we have.

I've found a detailed carb stripping guide (will check if it's the same you mentioned Ash) & will consider doing the full job (at least I'll be able to make them look good even if they prove tempremental). I've also read of a contact in Holland (I'm blanking on his name atm but have written it down at work - Van Der G... something) who sounds like he does a cracking job at fettling them which could be a fall back option. I like the idea of the hex headed screws! I've done the same to the engine with SS replacements (the old ones on there seem to be made of brown cheese). Is there any resource that specs th various sizes, thread types etc. of screws, nuts & bolts throughout the bike that will help in finding, as well as replacing/swapping, them as the bike slowly goes back together?

Hi all,

Having found the name, does anyone know how I would get in contact with Gerban van der Meer, if required? He sounds like the kind of carb guru able to bring a set of cantankerous PD46a carbs back to their (questionable) former glory.

Cheers.
