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.

Thx for the data!
The IDA's that came with the car are clearly not the original's (not IDT's), so I"m not surprised to find things that a different from stock. My main goal is to have a set of carbs that should be reasonable once I put the alternator (and all the other crap) back on the car. (it started off as a quck morning project while the air temp got warm enough in the car port -- now my house smells of gas. Sheesh) I believe the current engine has a stock cam (or something near stock) so I'll use the stock secondaries (damn - means I have to take both sets apart... ah well.. it's a saturday) Your recollections on the stock venturi's agrees with the P manual. I have a choice between 30's (just took one out of the original ida's) or the new ones, which are unlabled, but clearly larger. I'm thinking the 30's make the most sense. For Emulsion Tubes, I'm picking twixed F3's and F26's (dunno if there was a typo in your post) I'm leaning to the F26's since I have to dismantle all anyway -- this engine is not an S engine. kim. |
