length of idle tubes

[stevef]

The new idle tubes in my HP kit are about 1/8" shorter than the original tubes that I pulled out of a 17056262 carb. Does it matter? Is there an ideal length of the assembled down tube from top of collar to bottom of tube? In the photo, the right one is the new one.

I dont think it will matter. They are both WAY down in the fuel level.
Are the collars equally down on the tubes?

Thanks for your reply. Yes, the tubes are nearly equally down inside the collars, but not exactly. I positioned the assemblies next to each other in such a way so that the tops of the tubes that are inside the collars are even with each other, for a good tube length comparison. It's the tubes themselves that are different lengths, and not so much the collars. I realize I could knock the new tube down further inside the collar to get an overall length closer to the original, and even knock the collar deeper into the hole in the carb body, so the tube hangs deeper down in the hole. Just wondering if it matters. Could the fuel ever get so low that a 1/8" shorter tube couldn't reach it?

I say go ahead with it. The shorter tubes may even better as they
are less likely to hang up in the well if overdriven some time later.

End of tube should be flush with collar.

Thanks quadrajam.

Thanks Kenth. Any opinion on the length difference?

[Kenth]

Too small difference for any impact on function.

IMHO

Thanks Kenth.
