British Bikes / AMAL 289 questions
« on: August 03, 2020, 07:39:00 PM »
Hello - I'm new on here, searching for knowledge.
I have an application for AMAL289 carbs mounted horizontally, eight of them.
OK it's on a car - please don't throw me off just yet.
The questions are:
a) what is the purpose of the tiny hole in the casting just above the mixing chamber union?
b) when mounted horizontally, how far below the main jet centre line should the fuel level be?
I'm a bit old for bikes now, but went through a 1956 Sun 125, 1953 BSA B31, 1935 Norton Inter, 1938 Vinnie Black Knight (never had it out of third in anger).
Hope you can guide me on the paths of righteousness.
Neil.
