Needle valve & seat - keep or replace?

[CamoKing]

 

My carburetor rebuild has hit a snag.  Could you lend me some expertise with regard to replacing the needle valve and seat??  THank you again for any help.

 

 

On the left is what the KIT has offered; on the right is what I took off the carb.   It looks like I could use the KIT version.  They are equal in length/ pin to base....But I can't figure how the heck the supplied spring thing fits on it?  Is there some other way of holding that needle in?   

 

Before I do something awful I need some guidance as to the 'ins & outs' of a needle valve and seat for this Hitachi DCR342 I am trying to rebuild.

Also, is there some place I can get a replacement/new fuel screen??

I might be assuming incorrectly that spring wire is supposed to hold the needle in place.  Maybe it just 'links' the end of the needle with the tab of the float?? 

Set up like this:

 

Installed like this:

 

 

Am I headed in the right direction?   Time for a coffee break!!

Look alright to me. Clipping to the float allows the weight of the float to pull the needle down off the seat when the fuel level drops and also prevents the needle dropping out to the side.

 

The screen? I just pull them off old carbs. Wasn't there a new one with the rebuild kit??

Thanks, Mike.  There was no replacement in the kit from Auto Zone.  Do you know of a kit that includes one??

No I don't. A good kit starts at $25-$30 and probably would have it. The older carbs were brass screen.
