Right peeps, always knew my car was overfuelling badly it didnt used to be too bad but its gradually got worse.
I suffer from the following
1, poor fuel comsumption
2, badly sooted plugs
3,car bogs down under load
4, engine gives off a massive back fire when i turn the engine off
Hooked up a wideband today and the afr readings were shocking
normal driving is around 12.8- 13.5
WOT is 10.6- 11.5!!
would leaning off the mixture screw make any difference??
what things would cause the carb to over fuel as bad as this.
I havent looked at what size jets are in the carb yet, previous owner just told me the carbs set for standard boost but looking at the afr reading it must have a massive main jet in there surely
really really confused
