Bing main jet sizes
« on: January 15, 2019, 05:44:41 PM »
Can anyone tell me if bing main jets are rated by size or flow? Is a 185 main for example a 1.85mm orifice?

Thanks

Pretty sure they are flow numbers. Years ago I did some measurements and came up with 185 bing is about 1.70mm and a 170 bing is 1.55mm. I have drilled some to get different sizes which worked quite well.
