Carb Rubbers.

[porndoguk]

Found the best method from somebody on here is to get the front two in first then seat the rears with careful use of a small screwdriver around the rubbers whilst pressing down on the carbs. Works well only took 5 minutes to get them on.
The first time I spent hours with bits of wood cursing etc... The above method works well for me.

Thats the method i use i even did a youtube video to prove how easy it is :D
