What about that tool that attaches to the outside of the IDA, fuel flows into it and rises to one of two lines. I just got one from Jay Cee I think for about $40. Haven't tried to use it yet but you unscrew a plug on the outside of the carb float bowl and attach this tool to see how high the fuel gets in the float bowl.

Has anyone use this tool. I seem to remember it is a Porsche tool.

Thinking through my reply there, if I don't give it some down movement the needle will never open . . . So, is there a 'too far down' setting? Or should I just make sure it goes far enough for the full needle travel?

After looking through the Berg instructions and the HotVWs article, I finally found my Weber Tuning Manual. It says that "Check the float maximum lowering position: The needle must travel a distance equivalent to slightly more than the diameter value (in mm) stamped on its seat."

Setting the float level on a 44 IDF is a cinch compared to this. I hope I can come to comprehend this because I just picked up a set of IDA's to put on my motor.

You set them without the gasket.

Two points for guessing how thick the gasket is supposed to be:

Bruce wrote: The distance is set by changing the thickness of the gasket between the valve and the carb top. Spec is 25.0mm.

...... Although my tool looks adjustable, it is only adjustable to get the setting according to Weber's spec, 24.2mm.

The tool on the left is used to set the distance from the carb top to the tip of the inlet valve like this:

The distance is set by changing the thickness of the gasket between the valve and the carb top. Spec is 25.0mm.

The tool at the far right of the top pic is used to set the distance from the float's tab to the carb top. Although my tool looks adjustable, it is only adjustable to get the setting according to Weber's spec, 24.2mm. Here it is installed:

Then when the carb is turned upside down, the float "rises" to touch the tool like this:

Finally, the last tool is used to measure how much above the carb top the float rises to:

Note the slot machined in it. This is to clear the seam of the float. The tool has this machining on both sides, one is machined so the step is 5.5mm, the other is 6.0mm. The spec is to have the 5.5 touch the float, and have a gap for the 6.0 side.

Hey, Bruce - May I rent those from you?
