Can pilot jet screws be set differently between cylinders?

[hornet_guy]

Hello,

I noticed that not all of the 4 pilot jet screws of my cb600 carbs are set in the same position. Just looking at the screw head, they're at different turns.

As far as the little I know, this doesn't makes sense to me. Is the any case where where this can make sense? Am I missing something?

Thanks

The only way to find out how far the mixture screw is turned out is to turn it all the way in and count the turns. Each carbs is not going to be identical on the screw threads and their orientation.

So no, they should not be set differently. That said, they may well be set properly, which is not the same as the slot on the screws all lining up by eye.

Is there any reason to think there is a problem. Erratic idle, misfiring on one or more cylinders etc?

If not, leave them alone.

No reason why not if the manual specifies it. Some IL-4 bikes have larger idle jets for cylinders 2 and 3 to run them slightly richer.

The pilot jets may be different between cylinders, but the pilot screws (or mixture screws) should all be the same number of turns out.

You wind each screw in until it lightly seats. Then wind them out the specified number of turns in your manual, and leave them alone. Doesn't matter what the screw head looks like in relation to each one. Only the number of turns out matters.
