450 carb not going back together smoothly

[Mike]

That looks the right way to me... can you see anything that is obstructing it?

It looks like there's a lip on the inside of the hole it sits in.

If anything, I've got two more float bowls already on their way, so I'll check to see how those fit.

I appologise if i'm wrong, with my carb the o-ring end is down in the body.

I may have narrowed it down. With the needle jet out and sitting in the float bowl where it should go, it stops about 1/4" from where it seems it should go. I'm assuming it should sit flush down on the surface there?

You have it installed upside down. The "O" ring goes into the body. If the "O" ring stuck up in the air, it couldn't seal anything could it? LOL Turn them over and tap them in ....lightly... using a small block of wood and a SMALL hammer if they absolutely will not press in with your fingers. Do not strike the jets with the hammer, hold the wood over the jet and tap the wood.

The jet is in correctly.

Yep, that's in correctly. The O ring end goes into the carb body, whereas that pic is the float chamber.



So, silly question... do you have your gasket on?

I'll grab a picture tonight with the float bowl sitting on there to show where it stops.

That'd be great because I'm a bit stumped thinking what could possibly be stopping them from going on smoothly.

There's only two things I can think of...

- The needle jet is not sitting correctly in the carb body, meaning it's butting against the main jet.

- The main jet is the wrong type or something like that so it's butting against the needle jet.

This is the only pic I have of my jets (and pilot air/mixture screw), and it's not the best I'm sorry:

Got the two new bowls in the mail today that I ordered off ebay. Put them on, and they slid all the way down, no problems.

Strange.

Well that's a good result... but weird! They're definitely the same model float chambers and everything? That is just truly bizarre... so what's the difference?
