Carb Help PLEASE!!!

GREETINGS FELLOW BIRD LOVERS.

This being my first post here, I wanted to begin with a friendly Howdy!

Now the question, I've got a HUGE problem :sad: . I damaged a neddle jet cap on carb #4. I'm not sure the terminology is quite right 'cauz freakin' Honda (:evil: ) doesn't list this part. I'm actually talking about the small solid brass cylinder that sticks out of the main body of the carb and that the needle slides in and out of. The last orifice the fuel comes out of before going through the air funnel. It is said to not removeable...well I've got it in my hand and it's broke. The tube is about 1/2" in lenght 1/8" inside dia., and has a tiny rubber O-ring at the end of it. It's basically the 1/16" brass lip that sticks out of the aluminium body into the air funnel. I do have pics of my part but dunno how to post them!

I know Factory-Pro carries some of these aftermaket "non-removeable" neddle jets but not for our dearly beloved!

If anyone can help finding one of those (or has a used carb at a kickass price) please let me know...I don't like the idea of getting ripped of by Mr.H for a 400$ new carb cauz these bast... don't stock what is probly a 3$ brass tube!

If you think you know the part I'm reffering to but wanna make sure , send me an email and reply some pics

Thanks a bunch!

'cauz I'm a dumbass :roll: !

The carbs were off for re-jetting and a screwdriver fell in the tube and scratched it a bit, I THOUGH "well lets try and gently take it out and sand it off..." but of course a soon as a pair of needle nose pliers came close to this tiny piece of brass, it dented! So then I THOUGH " well let's pry this little bugger out and replace it with a brand new one, I 'll stop by the shop on monday..." that was a month ago. I the only scarp yard anywhere close to here is probly one of the worse crooks on the surface of this planet... He says he's got a set of carbs that he's not willing to split..and he'll gladly sell it to me for 500$ :devilfinger: . He's even worse than Honda!

Busted out my HONDA manual and the part you snafu'ed is called the needle jet holder. A brass tube with lots of tiny holes all around right?

If that's it, it unscrews from the float bowl side, after the main is removed. I would think Honda would sell it seperately, but then sometimes they are big on assemblies of parts being the only way to get it. You have to watch, parts guys are comission, they WANT to sell you the Whole thing. Not just a little part.

hey guys,

thanks for the replies but the diagrams are the same I've been seing lately, the needle jet is not there...what these guys call the needle jet is in fact the "emulsion (or sray) tube" (thin brass tube with tiny holes in it that's about 1.25" long and holds the main jet). What I'm lookin for would only be seen from an "inner venturi view"!

Here's a view of a similar carb.

Look at the part where they say "Needle Jet (Collar)"...That what I'm looking for! Any Help?

Hey big nick, most, ok all the carbs I've worked on, the needle jet collar you're referring to has been physically part of the emulsion tube. You remove the top cap, diaphragm/with needle, the float bowl, and main jet, usually the main jet holds the emulsion tube in place and after the main jet is removed the emulsion tube slides up out of the venturi through the top cap. I don't think it's listed in the fische because they are both the same thing. If this is the case you should be able to remove the main jet and finish removing the emulsion tube. When you order a new one I'd get a new jet too, the other one may be warped from pulling on it. Hope this helps.

Thanks Andy. Are you saying that if I order an emulsion tube, the needle jet would be included?

where it goes

When in place

The Keihin is pretty much steup like the pic below, the emulsion tube and needle jet are seperated and are not set in te same 'passage' (they meet at an angle.) Note that in this pic the "collar" should look like this firts pic I posted up there!

Try this, its a french site(english part) that sells all Honda parts from the microfiche the address is for the bird carb fiche page with all the descriptions below, may help to identify the part. If it wont let you in just go to the main page and register yourself, its free. BTW the prices it shows are in Euros.
