When you say it won't come out, do you mean it won't unscrew? Or it does unscrew but won't come out?

It wouldn't come out cause it had been stripped but I wasn't one to let that stop my unyielding machismo and i went and bought a better screwdriver and now I've got them all out. probably going to replace a few/all of them though after seeing how chewed up they are from the last owner. On to the next step but so far all of the jets have been very clean and the main jets even look brand new.

Easy fix for those Trey.......run the slotted top-side across some emery paper set flat on table or whatever to get past the burrs, take a dremal with a cut-off wheel and re-slot. Got alot of distance to mess with there, so don't worry bout that. Slotted screwdriver side will look and work like new!.....don't forget to replace the teeny o-rings and make sure the teeny washers are there. They are also available as a Suzuki part # same as the o-rings. Before assembling that portion, put a very lite film of anti-seize on those brass threads and run them in and out a couple times to smooth and clean up the aluminum threads in the carb casting, then put the spring, washer, o-rings on...in that order.....hope that helps!

I have none of the tools you just mentioned haha. How much for a replacement and where do i find one?

[XSTrey11]

Ran into an interesting problem. When cleaning the pieces of number 4 i was looking into the "Main screw" (the carb cleaning 101 thread calls it that or a seat for the needle in the diaphragm assembly.) When looking into the top (where the main jet came out of) there seems to be the remnants of a broken off main jet. I imagine i should try and get it out of there but I don't know how. So...what should i do?

[petejw]

hi trey,
just to let u know, when u have fuel leaking into the crankcase/ or
leaking out of the air box,
u either have a leaking needle and seat or u have fuel leaking
from the 'o' ring around the seat.

im not to sure what u mean by the main screw, i think if ur
refering to the emulsion tube, the top cap and slide diaphram need
to be removed, with the carbs upside down and the main jet removed
u can then tap the emulsion tube, using a wooden dowel, or i use a
phillips screw driver and push the emulsion tube out, it comes out the end
the slide goes into.

hope that helps.

Ok, as to new pilot jets, you have a number of options. You can go to your local yammie dealer and pay about $4 a piece for them - make sure you tell them to get the BS30/96 style and NOT the VM or N151 style!!! If your looking for all new jets for the carbs, the best and most economical option I know of is to go to Ebay and find seller by the name of Georgefix. Let him know the year of your carbs and he will make sure you get the right kits to jet them for stock.

As to the piece of a main jet stuck down inside your emulsion tube, assuming this is what your saying, that where the main jet screws in under normal assembly, there is a small piece of something stuck down in that hole? I would use a pick or somthing like it to try to dig it out carefully.

yes it's the emulsion tube! sorry about that and yeah what i think it is is the threads of an old main jet or something that's been broken off in there and the current main jet just screwed in on top of it. its just a few threads of something that got sheared off in it. Also, the needle on one of my diaphragm assemblies is bent just a tad on the bottom. will this be an issue? I hope not because I hear those assemblies are quite expensive.

[DGXSER]

The needle jet is a separate piece from the slide and diaphram, it is mounted in the slide, but it will come out. A bent tip is not a good thing....ever So you need to straighten the tip as best you can and or get a new needle jet.

If your main jet screws in nice and tight with the threads as is, I would not worry to much about what your describing.

It doesn't get quite all the way down...so i guess i need to but new pilot jets and a new needle jets. And figure out a way to get that thing out of the emulsion tube.

Trey, is the piece of broken jet tip still threaded in the emulsion tube or is it loose inside the tube?

If it's still partially threaded and the new jet was just screwed down into the emulsion tube on top of the broken piece then you might be able to back it out and remove it with a small metal pick, a small left-hand drill bit or, as a last resort, an EZ Out. Be careful. The emulsion tube and broken jet are both made of brass so they're soft and they can get mangled quickly and jam. EZ-Outs are made of hardened steel that is stupidly EZ to snap off in a hole, especially the small EZ Outs like the one that would fit in a broken main jet tip stuck in an emulsion tube, and they're not so EZ to get out when they break. Also, EZ Outs expand whatever they're put into and the broken jet tip would jam in the emulsion tube threads in a heartbeat.


If there is actually piece of a broken off threaded jet tip loose inside the emulsion tube you might not be able to get it out at all. Unless it's a very small piece none of the holes in the emulsion tube are big enough to get a complete broken jet tip through them.

You might be able get the threads of the broken tip to sit just right and start them back into the threads in the emulsion tube. Then you can try to unscrew it. If not then it's basically stuck inside the emulsion tube forever.

It's threaded and the main jet was just screwed in on top of it. I can see the threads of it through the bigger hole toward the top of the emulsion tube. I guess its not the end of the world to just replace the tube if i screw it up trying to get that broken piece out. I don't really have a tool that i can think of to try and back it out with.

[motoman]

Either way, gotta get that piece out. Needle won't reach jet in proper taper location. That IS a measured distance, and the threaded part doesn't count!

[DGXSER]

Verify you CAN get the replacment before you go to far with it. Some of those buggers are no longer available but in the used market.

[XSTrey11]

JOYYYY!!! I just got it out!


I used a tiny hex head screwdriver that just fit inside the broken jet and it back right out! Feeling so accomplished!!

[XSTrey11]

Now that the emulsion tube is cleared out the jet will only screw in this far. I assume this is correct?
