2 questions about f1 carb settings
« on: June 13, 2011, 08:20:37 PM »
having problems with my carbs so i bought a set on ebay, described as all linkages free etc. when they arrived they were seized solid.
luckily my ultrasonic cleaning tank & new chemicals sorted them out. (it's bloody great)

2 questions

1) when i check the float height, is it with the tiny spring inside the needle jet pushed into the needle jet as when my carbs are upside down the weight of the float pushes it down.

2) the haynes manual says carb needles set on 3rd notch. (they have 5 notches so is it 3rd one from the top or 3rd one from the bottom)  or should i just toss a coin !

Float height is with spring tip NOT compressed
