In the workshop manual it says that the throttle needle should be in position 3. Does this mean the top notch or the bottom notch?. I am fitting new slide, needle jet & needle so it should be as per the manual. Any help appreciated.
Needle slot positions are counted from the top of the needle.
:)Many thanks for the info.
The needle on my B175 carb has only got 3 slots- and it runs best on the bottom one....
