Cause popping/back firing from the exhaust?

Nice one... I think I'll have it checked by the pro tomorrow and then have the emmisions checked on an emmissions analyser, tis usually how the garage tunes my car but I let someone I thought was a pro do it by looking into the combustion chamber and making sure the flame was blue.PNL said:Yes your plugs may be OK mate but the dirty or white deposits give you an indication of how the carb is tuned Black = rich and white= to lean could be just the case of tuning your carb to get the fuel to air ratio correct

No adjustment can be made to compensate unless I increase the size of the Jets in the Carb OR reduce the size of the induction kit.
