We are converting a stock 2 liter 4 cyl from D jet to Webers. My gut is telling me a 40 IDF with 32mm venturis is the correct starting point. I am considering purchase of a complete set of 44 IDF's, but are unable to locate 32 mm venturis. Assuming 32MM venturis can be found are 44 IDF"s too large for a stock 2 liter?
thank you |

Yes, I have gathered the same, these rarely fail, but my thought is to eliminate as many variables as possible. The Bosch system we are cobbling together is from several "baskets". I managed to clean up the case/trans today and couple them up, hook up a starter and try a compression check. 120 - 125 - 120 - 130 cold engine
Today was a good day in the shop, our new "rust free project" may be rolling down the road soon Thanks to all for the input |

I didn't read the whole thread, but my experience was that 44 Webers were too big for a 2.0L. My motor had Euro pistons, a sporty cam, ported heads, and headers. I was told 40's would've been better for that motor. Made nice power above 4000 RPM with the 44's though.
