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 |

@GN, I am considering using Webers on a stock 2.0 liter/4. It sounds as though the 44 IDF's with 36mm venturis are working well with your ride. Are you still considering changing to a Bosch D jet, or is that history?
Thanks |

Cabman -
Well, I'm keeping the Webers for now, and yes, they are running wonderfully - engine is out of car for last 6 months, and I hope to have it in by end of May. And while many say it's not possible, there are others who confirm that it is. Many say the 2.0 cannot run well on 44's with 36mm venturi's, but I know it first hand. Great idle, smooth transition to power, and downright bad in WOT. BUT, that being said, I have an original '76 2.0 D-Jet and I have to find out for myself which I prefer. The ECU and TPS are rebuilt and working like new, all other components just need to be cleaned up, have the injectors tested, get new hoses and a vacuum dizzy and I'm good to go. I think I could install the D-Jet in a day - but I know it might be quite a while getting it dialed in. Then I'll make a decision on which I prefer for my driving. I don't see that happening for at least a year - I've got tons of things to do on the car first. And I can be getting the D-Jet ready in the meantime. You can be sure I'll post all I learn here. While saying this, if I were starting from scratch, I'd put 40's on the engine instead of 44's. Too many say 40's are ideal for the engine. If you haven't bought the carbs yet. And if you don't have them yet, talk to Eric at PMB - he can supply them and you'd get his great support. He's a strong believe in Webers for the 914.
