Taking apart my carbs for cleaning, I found one has a stepped spray tube, and the other has none at all. 1974 850. Usual?
How are they attached in there, anyway?
 
Certainly not normal . Do you mean no step on one or no spray tube ? Each type needs a different needle. One carb has probably been replaced. What are the numbers stamped on the body ?

The tubes just tap out. It's best done with a double diameter drift after warming the body with hot water.

I must be losing it. I went out to check model #'s and looked into the jar where one is soaking, and there it is, a stepped spray tube, just like it's brother. Less caffeine, I think next time.
These can be drifted out from the bottom up?

Thanks!
 
No, from the top down once the jet holder has been removed. It has a shoulder on it.

We're talking about a gentle 'tick' here, not thumping it but you don't need to take them out unless you're intending to change them. They don't wear and aren't difficult to clean in-situ.
 
Thanks!
I'm planning on getting them resleeved, so probably need to strip them down all the way.
 
openroad, if you are going to the expense to sleeve your carbs, you may want to read through the link below and do this simple mod to the pilot circuit. It really is the only way to ensure the pilot circuit gets cleaned properly.
