i was driving at night for the first time ( new rebuilt L24) and noticed that at past 3000 rpm, I'm getting an awful lot of what looks like badly combusted gasses billowing from the exhaust.
It is NOT oil, as it doesn't have the blue tinge or smell, but more grey/back
Checked the timing with strobe and its spot on
When I pulled the plugs, they're really black ( but not oily), which leads me to conclude that i'm running way too rich.
The car runs fine otherwise and has plenty of power
i know that there are threads on setting the float levels and the mixture knobs, so I set them knobs to default 2 turns
is there someone in SE Melb suburbs with a C02 analyser
