Questions re: Weber 44 IDF carbs:
1. Is anyone running these on a stock engine, and if so, how do they perform? National Carburetors kit for stock engines is 34 ICT's, lightly modified 40 IDF's, and only 44's on heavily modified engines. 2. What problems do you introduce using 44's? other than dumping too much fuel in the engine...... 3. Venturi's are 45mm, someone pointed out that one should use 40mm venturi's - is that with a stock engine? 4. Anyone run 44's and then convert back to EFI? How did that go? Labor cost? TIA, GN |

That Allzim package is $3.5k (IMG:style_emoticons/default/WTF.gif) For a 2056 the 44s with a 32mm Venturi swap are the ticket. Cleaner transition. The 28s run out of steam.

I'm running 36mm venturi's with best performance by far and no issues. 2 years ago trying to get the 44's dialed in, I tried 32mm venturis as they were the recommended solution by a top 914 mechanic. I could not get them to work. Engine ran fine, but had zero power - no torque at all at any rpm or under any load. I went back to the 36's that were originally in the carbs when installed by the local Porsche dealer many years ago. Had idle problems that were solved by going from .050 to .060 idle jets. Dialed in carbs and they work great, all conditions, tho many say that's impossible. Torque above 50% throttle is great, below that is fine - very smooth acceleration, no stumbling.
