Completely unable to remove pilot jet

[Mike]

Whoever got in there last left one of the pilot jets with half of the top missing, making it impossible to remove with a screwdriver. I soaked it with PB Blaster and tried an easy out, and all it did was hollow out the jet. Any suggestions to get it out without destroying the float bowl as it doesn't seem like any place sells just the float bowl?

What type of carburetor has the pilot jet in the float bowl?
Mostly they are threaded into the carburetor body?

[ddaniels]

Why would you destroy the float bowl? The jet is up in the carb body. Soak it again in PB blaster, apply some heat to it with a little propane torch (make sure it's free of gas), then try a left hand drill bit that's bigger than the hole in the middle of the jet, but smaller than the outside diameter of it. That worked for me when I couldn't get one of mine out. The left hand drill bit turns to the left and should grab hold of the jet and twist it out if you soaked it long enough and put enough heat to it. Good luck. I know it's frustrating, but when you see it come out, you get a real nice warm and fuzzy good feeling. Stay with it, it'll come out.

You can use a slightly larger left handed drill bit, larger than the easy out and see if it will grab hard enough to catch the remaining portion of the jet...

Ive never had good luck with those easy out things. Usually my approach would be to drill it out Im not sure if carbs would be to delicate, but if nobody can thing of anything else it may be your only option.

I've used this technique on some carbs and occasionaly the "smashing a screwdriver into brass" technique as well. Now what in the world has a pilot in the bowl itself?

[Mike]

Errr, maybe I'm referring to it incorrectly, but in this link: http://members.dslextreme.com/users/...ning_guide.pdf

On the 8th page, it's saying to remove the pilot jet from the float bowl.

post a pic of what your working on please.
The alloy of a carb body will not forgive much abuse much like a brass jet.

Still have not seen what bike we are working on, but aren't the jets for the 450 carbs in the bowl?

I know I have seen a set of carbs recently that did, I think they were on a 450.

Yes - it's on a 450.

In the link I just posted, it has pictures showing exactly what I'm looking at.

From the sounds of it i am interpreting this as they are referring to the "inside" of the float bowl area, and thusly "inside the float bowl". This would logically go on to mean that the pilot jet is in it's usual spot. I cannot fathom the inefficiencies of a carb layout with fuel paths heading down to the bottom of the bowl, that just doesn't make sense.

And while i'm at it, which easy'out are we talking here?
This?


this?


or this?


I've used all three and the square punch ones (you only lightly tap them in when in light metals like this) grip far better than the helical ones, which grip far better than the "thread" ones.

Having viewed the picture I'd say, left hand drill bit or ezout. Nice and slow. Good luck. Have I told you how much I detest soldered floats?

it was the first one. i'll grab a square one tomorrow and see if I have any better luck.

[blowerbike]

i have posted it before.
here it is again.
us a TORCH..not melting it but heat it good.
penetrating oil of any type has no effect on stuck jets.
an easy out is fine to use once you heat it up good.

Yeah, but the link you posted was for the entire document. If you don't have a quick internet connection, the time it takes to load the entire document is not worth the wait.
