In cold weather (less than 5 degrees Celsius), after the car has been started for roughly five minutes, the FBH produces masses of acrid white smoke / fumes. So much so that one might think that the car was on fire. These fumes disappear after a further few minutes.
There is a mod which inserts a fuel restriction in the fuel pipe but I can't see that is the problem in this case.
Can any FBH gurus help please?
