Weber 40IDS Problem Solved
 

If you remember the earlier post about the hi speed lean problem with my Weber carbs, well it has been solved. The small tab on three of the floats had depressions from the old needle valves wearing on them and when new needle valves were put in, this caused the floats to stick low so fuel level was way too far down. The shop rounded up 4 level gauges and watched the fuel level and it would drop some and then stay down. Putting in 3 new floats cured the problem and now the hi speed enrichment circuit gets enough gas! The wear marks can be seen if you look very carefully at the float tabs.

good thread

Why didn't you post this on the original thread?

After a long thread, the solution tends to be lost inside and since the solution was sort of unusual I thought it would be best to put it by itsself. From what I have noticed, many, many times the original poster never posts what finally happened or what the cure was.
