here's hoping someone can help, so the engine is a Rover v8 vitesse 3.5 running a viper cam and has an edelbrock 500cfm carb and edelbrock performer manifold fitted. carb at present is running the following jets and metering rods
prim jets 0.86
sec's jets 0.93
Rods 065 x 052
The issue is its running very rich, plugs are black and so are exhausts, now car runs sweet above 2k, but is a pig on tickover and also hunts really badly below 2k, i did think it could be an ignition problem, but have installed new leads, dizzy, cap, rotor arm and also coil, have had a look around the internet and from what i read jets and rods are bang on the money, but the secondarily jets and springs are wrong, advise shows sec's @ 83 and springs should be sliver, now do the sec's control low end power??? or should i adjust the mains and rods, if so by how much????
any advise welcome
