Folks,
I picked up a set of IDA's in good condition that were set up for a 2.8 (maybe an RSR?) -- anyway, the IDA"s on my /6 have throttle shaft issues, so I figured I'd just swap some parts back 'n forth to get the correct setup for my stock 2.0L /6. Turns out my original IDA's weren't exactly stock either. There are several parameters here. Idle jets are currently at 55 on both carbs. (stock is 45) I'll be using 55 initially. Mains are 125 on my current set, 155 on the new ones, stock is 105. I'll be using the 125's. Emulsion tube on mine are F26's (same as 911L), and on the new ones they are F3's (911S). The originals used F1's. I've no clue which one I'll use -- if I'm lazy, I'll leave the F3's in there. Air correctors are 180 on both IDA's. Original's used 170s. I'll use 180s. Pump Jet is 50 everywhere. In the picture you will see two different auxillary venturis -- the shorts ones are stock /6, and the tall ones I've not seen before. No clue what to use. Lastly, and I've not got this far as I have to cut wires, but from an eyeball estimate, the actual venturis on the originals were quite a bit more restricted. I'll pop both of them out shortly to see what they are --- i'll use whatever is closest to the manual I guess. Comments welcomed. kim.

QUOTE(Gint @ Feb 8 2004, 08:53 AM) Excellent info! I've taken the liberty of resizing the pics in this thread to make it more readable. Purely slefish you understand, as I will use it later for reference due to the quality of the information. I may even move this thread to the "Classics" section. As usual, Kim asks questions and receives responses that I (and almost certainly others) can use as future reference. Kim, If you need the numbers from my carbs, just say the word and I'll traipse (sp?) through the snow and dig 'em out of the shed and take them apart. Thanks all! Doh. I was thinking of taking my time and shooting the pics -- but mostly I was trying to do the least I could to get back to assembling the car. I ended up taking nearly everything apart. I decided the main venturies needed to be the stock ones and a lot comes apart to get to them. I meant to shoot pics of the two emultion tubes, as they would be an interesting comparison after having read the emulsion link from Marc. It was too late of course, as one of the sets had been reassembled already. Anyway, I'm pretty sure that the carbs will be apart again in the future and I'll shoot some of the missing pics then. This has been a great thread tho -- I definitely appreciate the wisdom/info/btdt that y'all have been posting! Once the car runs, I'm sure I'll be re-reading this (IMG:style_emoticons/default/laugh.gif). Back to the garage! kim. |
