Reply to "Weber IDF's and Panteras"

I have been looking into IDF's a bit more again for fun.

It turns out there is a local VW shop near where I live (in Salt Lake City) that rebuilds Weber carbs. I talked at length with the guy who rebuilds and tunes Webers, Solex, Zeniths, Delortos, etc. I even compared first-hand IDA and IDF carbs and investigated differences with them both in my hands. If anyone is wondering, the IDF is about 4" tall from bottom to top of carb, not including the main jet extension. IDF's are made to take air filters, have the same jets as IDA's, and have four progression holes instead of the IDA's standard two. While the IDA can have another progression hole drilled, (the so-called "intermediate circuit") the IDF is the true street carb according to the rebuilder/tuner. The rebuilder/tuner seemed to like the Delorto carb that has the same mounting pattern as the IDF, but said that they are no longer being made and scrounging up four 48mm versions all the same would be much more expensive than four brand-new IDF's.

Four 48 IDF's are actually cheaper than four 48 IDA's...
