weber IDA 3C emulsion tube examples

[juanbenae]

looking for an image of a weber 40mm IDA 3C emulsion tube F11. ive done images searches for said ET but they are generally images of differing F11 tube that I believe are for the 48mm two barrel webers.. see here




here are the ET for the 40's. the newer is a F8, and the older looking one is an F3.




I'm fighting a lean on idle circuit and according to weber data the F8 could help. it has over the previously run F3's, leaning everything but sitting idle where I remain rich. even the freeway cruz AF numbers have leaned out to an acceptable level.

can anyone provide an image of the F11 I'm looking for? performance oriented emulsion tube section has me very curious of differing ET make up. other tube images would be appreciated as well.

The F11 in your photograph is indeed for a Weber 40DCOE and these are the tubes used in the PMO carb.

They won't fit your IDA3C and the only '61440' style emulsion tube designated as an F11 is 61440.281 which may not be suitable.

The dimensions of this tube are shown below:

thanks chris, but I have the image you've shared along with a number of others so I'm still looking for an actual image of the F11 tube. nobody has one in a jetting tackle box they could snap a picture of?
