I am in the process of tuning my car after a rebuild. I have dual weber 40's. My engine is a 2.27L. Everything is going pretty well. I am slowly getting the jetting closer and closer. I was driving around at about 60mph yesterday. The head were hotter than I like (325 degrees). I checked the spark plugs and they were bone white. The main jets were at 160. I increased them to 170 (above 160 I only have increments of 10). With the increase to 170, the car is running very well and the temp at around 60mph cruising is around 275. I sped home, tuned off the car and took out the plugs- bone white. I was quite surprised.
The main jet size sounds high too me. Does it sound high to everyone else? Is it possible that I am needing a high main jet size because of the float level? I have my floats set at 10.5 with the gasket. Any opinions would be greatly appreciated |

My idf's have 32 vents. I am definitely changing the main jets and not the AC jets. My idles are 65. Idle seems to be fine. I think that I have the mixture screws out about 2 full turns.
I also have a set of 34 vents. I stayed with the 32 vents because I thought they would be easier to tune. Is this correct? Should I just change to the set of 34's? I do have a metal lathe so I could shave them down to 36mm if needed. How can I tell if I need bigger vents? I would like a set of 44 idfs but I don't want to spend the money (my wife is getting fed up with my hobbies). If anyone is interested in trading a set of 40 idf's for 44 idfs let me know (IMG:style_emoticons/default/w00t.gif) |
