I have two different charts that give two different settings:
28 vents, 1.35 main and .55 idle or 32 vents, 1.45 main and .60 idle. Bought a set of EMPIs for a 2.0 which came with: 28 vents, 1.25 main and .52 idle Read MANY threads here, samba and type4forum on proper jetting and vents and they are all over the place. Would like to get these together and installed asap. Is the current set up good enough for daily driving to/from work? No track, no AX, just cruising around TN back roads. |

The only help I can offer is to share my experience with my 44idf Webers. My engine is 2.2 liter type IV. My carbs are set up with 32 vents, F11 emulsion tubes, 130 main jets, 175 air jets and 55 idle jets. When the engine was first built it ran great once past about 2200 rpm. Prior to that it would NOT come off idle very well at all. A change of Idle jets pretty much solved that problem. About the best advice I can give is to buy, borrow or steal something to measure air/fuel mixture. This device and test drives might help you decide the jetting combination you want. It may take a bit of experimenting (and patience) to find the best combination for your engine but I think you will eventually get there. Good luck.
Cheers, Elliot |
