race-it, listen to Eljaro, he is THE Weber guru, check out his posts. :)
A/F ratio with carbs has a lot to do with cam profile etc. Valve overlap has exhaust AND fresh air/fuel mix going down the pipes, the more overlap, the more this happens. The air/fuel going out at overlap doesn't combust very well being mixed with exhaust gas. Leads to high hydrocarbon and high CO emission levels. Unavoidable with carbs and big cams, more easily controlled with sequential EFI. My V8 runs 14.2 at idle yet smells of fuel at idle and burns your eyes if you're behind it up close. |
Did you get your 44's working!

Nah...they are sitting in the shed and a holley 4barrel now does the delivery....I want to sort them as they give the car wings......plan is to strip them down and rebuild.....wow what a waist of money buying new carbs.
JAC MAC can you email me that pic in a higher res.....I cant read the one shown......When I put the webers back on I made sure they where all closed and the transition holes where all covered the same. The dodgy carbs just wont wake up until the throttle plate is opened. We are thinking about drilling out the lead plugs in the idle circuit and making sure there are no blockages. |
