Hi All
Ive recently put together an almost standard 1275 and put it in my mini.
It seems to run quite well and I've worked out most of the kinks however there is one problem I dont understand.
For the middle third of throttle opening there seems to be a whistling noise coming from the carb. It is gone at low and full throttle and is only present under load.
I've tried getting the whistle while reving from the engine bay so I can locate it but no luck.
Any suggestions on what it could be?
Or is it normal?
Thanks in advance!
