Alex_H Posted February 1, 2012 Report Share Posted February 1, 2012 Hello, Just a quick one really, I need some smaller jets for my ccm, and they'll be mikuni ones. I know they come in 2 different head sizes, 5mm and a smaller size, but does it actually make odds to the fuelling if you fit either size? They're the same thread and I guess the same hole size?

wazrs257 Posted February 1, 2012 Report Share Posted February 1, 2012 If the head of the jet is a different height, it will affect your effective float height. Get in touch with Allens & order the correct one. Link to comment Share on other sites More sharing options...
