    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

So in my cleaning endeavours, the carb that came off of the grotty set i bought off of ebay has a blocked pipe, searching on here i think it may be called an Enrichener passage? its a small tube that sticks up just over from the pilot jet tube, and goes into the float bowl, thus feeding it when the choke is pulled open.

it is the tiniest of holes and i am just wondering if anyone has any suggestions of how to get this tiny passageway unblocked, ofc i am trying the soak it method but i don't at present have anything small enough to poke down it, is this the only way, just time and patience and hope that the soaking will do it?

I do have a compressor but it is only a hobby one, so not that powerful, but i am periodically trying to blow thru it with that.


GS550L 1980, Mikuni BS32SS carbs

thanks for any hints and tips
 
Have you disassembled the carbs and soaked the bodies in carb dip? Do they sell carb dip in England? If not, do they sell that Yamaha carb dip stuff that mixes with water?

You don't need a powerful compressor, just one that gets to 90 psi or so. A single strand of thin wire typically helps root out those blocked passages. Stainless steel wire typically used for wire tying aviation hardware is about the right thickness but measure to know for sure.
 
Yep, after a good soaking in whatever chemicals you have available, poking with a single strand of multi-strand wire (I use copper) usually does the trick.

I have a couple different sections of wire that I use. One has thicker strands that I use for the main and needle jets, as well as the side holes in the pilot jets. I have another section of wire with much thinner strands that I use for the "choke" tubes and the tips of the pilot jets.

.
 
yeah i am soaking it, just need to find a thin enough piece of wire now then
 
Just strip back a few cm of insulation off some wire to use single strands. Might have to find some different wire to get some thin strands, but that's OK, you will need at least two sizes anyway.

hmm, did that to an old extension lead we had laying around, fits but its so weak and bendy that tbh it's not much good, the hunt continues

trying to get this fluid down into that tiny hole is being a real pain, but from the other end it all just flows out everywhere else
 
Soak it real good and use the air to blow it out. maybe a wire from a bread tie wrap will work. And be sure to soak the bowls and poke the hole out in the bottom of the hole the pick up tube sticks into. The hole at the bottom allows fuel to get to the tube, so it too must be clear.
 
Rudeman i think the old man would kill me if i started canabalising his guitars of their strings LOL

good news managed to find something and its free and clear, so now with that being the last bit time to rebuild them and put their shiny new jets in place :D

Hopefully tomorrow can get them onto the bike, fingers crossed all goes well, it's been a long hard slog getting her sorted out this last year :D
