Title: needle out of emulsion tube?
Post by: xanthras on August 25, 2009, 02:17:28 PM
What are the chances that when you are turning the carbs in all directions to get the throttle cable back in that one or both of the needles come out of the emulsion tubes? I cant think of any other way this could happen. Anyone? And if this did happen, and was not corrected before re-installation, would the bike start and idle pretty much ok, but then run like crap when you opened the throttle?

I'm not gonna go into all the details of why I am asking, I will just say that as someone new to carbs I am learning alot...sometimes easy, somtimes the hard way...

The needle will come out of emulsion tube only if you dont have the needle retaining piece ...
If it wasn't installed properly when you open and closed it ...
Cool.

Buddha. Could you give me a little more detail on the needle retaining piece? The needle never seemed all that secure to me. Once I gently removed the diaphram and set it aside the needle just dropped out. There is some piece that is supposed to hold that in then? Is it connected to the slide guide or under the diaphram? I am having a hard time finding it on my carb diagram. Thanks for the response. I am sure you get sick of answering these noob type questions...

The needle retaining piece i believe he is referring to is the setup of washers and plastic piece that fits into the top of the slide after the needle is put into place and is held in with an o-ring and has a spring on it to keep pressure on the needle.

I have the newer style carbs but am pretty sure their is a very similar piece for the older style carbs.  It goes in where the 14th picture is showing on the poor man's jetting tutorial is showing.  That is the older style carbs.

Needle is pushed in with that spring ... the spring sits on top of that round button shaped object and that button sits on top of the spring.
I'll send you one for $2 mailing ... or you need 2 ?? yea sure send $2 ... I lose these a lot, cos they tiny and they roll off somewhere.
Cool.
