Topic: Stripped screw in carbs

[narcoticrex]

I took apart the carbs on the 76 750 last night, and on carb 3, one of the screws taht hold in the needle jet is stripped!  What now!!?

Also, should you be able to look through the slow jet? All 3 of my carbs i disasembled, you cant see through it, but i stuck a needle in there and it feels like its meeting metal?

The slow jet is a tube with a restriction metering orifice inside it.  Yes, you should see light through it.  No, don't be poking inside with sharp tools that will damage the orifice.  The orifice is about 0.016 inches in diameter.  At least use something smaller to poke in there, if you can' simply blow through it with a carb cleaner pressure nozzle.

The carb bodies can be tapped for the next larger sized screw.  Then keep the gorillas away from your carbs and screwdrivers.

thanks twotired, im working on the smurf....

question:  what if I dont have a tap?  and what if ive never tapped anything before? 

Another question:  The slow jet (the ones clogged) are different.  1 and 2 have what I guess are normal ones: number 3 has a weird pattern of holes, that are angled and circle the jet.  Is this normal?  I dont think it is, but it never hurts to ask, right?

TwoTired, you answer so many of my questions i should just have a red phone with a direct link to the TwoTired cave - thanks, i appreciate your time.  no, im not going to ask you out to dinner.

Do you have money for another carb body?
Do you care that people will point and laugh?  (what am I saying? You bought the smurf.  )  Then see if there is room to put a nut on a longer screw through the body, and glue some rhinestones to it.   Or, investigate dry wall screws. 
Or, buy a tap and learn.

I don't think so.  The carbs are all supposed to behave the same way.  How can they do that with different parts in them?  Check the numbers stamped on the carb bodies.  Maybe you have a set made from different models?

Dang, and I was getting pretty hungry, too.  Dinner would be fine.  Just don't think you can have your way with me!

The slow jets should all look the same. The kind I'm imagining are a combination metering jet and emulsion tube, the emulsion tube has a few really small holes drilled crosswise through the tube. Your main jet also has an emulsion tube, it is separate though and includes the needle jet orifice - if you (gently) tap the needle jet orifice down from the carb slide side, the orifice and emulsion tube part will drop out the main jet hole. The cross drilled holes tend to fill with gunk. They should be cleaned out to get proper carburetor operation. Using single strands of copper from lamp cord type wire to poke through these holes shouldn't damage the parts.
You can try a thread repair kit, I don't know how well the glue like substance that forms the threads will like a gasoline bath though. Tapping the hole is not a hard job, the metal is very soft and easy to work with. Maybe this is not the best way to learn how to do it though?

At least not on the first Date

this is the difference in jets - looks like one got mashed, but it appears to be a different design too.

and twotired....you dont put out, you dont eat out.

I've never seen jets buggared er, distorted like that.  It's a tiny emulsion tube.  Doesn't seem like it would work right.  Better use my dinner money to get yourself some normal ones. 

You're not gettin' my red phone number either, but we can still be "just friends".
