31/10/2005 14:26:49   Louis   Hi there, some time I haven't posted! I have just aquired a "new" 96 v4 (a 1976 rubber bumper model)... I need to adjust the carb, I once read a great trick for adjusting using wd40 and spraying it into the intake and adjusting according to the reaction of the rpm... Is this daft or is it a reconised method? Can any of you tell me more?
Thanx for the advice ;-)

You've only got idle speed to adjust in addition to this as all the jettings will be correct if it's standard. If it's not standard, get a Weber.

I had my Swiss "MOT" yesterday and they always check the CO level and the chap told me that I was running lean :-( that is why I want to adjust the carb... It also is running a bit rough... I think I should send an update of photos as the gallery ones are rather old ;-)

colortune is a special spark plug which allows one to see the colour of the combustion within the engine and adjust accordingly.
