Carburetter Attachment?

Postby Mick D » Sun Oct 04, 2020 4:26 pm


I'm trying to sort out the carburetter attachments on my G15CSR. I've sorted the stud dimensions but from the parts list the carbs appear to be retained by three studs and a screw, the list also details nuts, part number E3231.

Can anyone advise what this nut is? I know it's a 5/16" BSCY thread, but is it a reduced hex or some other variant? and could you advise of the location and type of the screw, (I assume it will be a 5/16" 18TPI Whit screw but what head does it have?)

Regards Mick - (Currently also struggling to part the crank cases :x )

They are reduced head nuts and again you are correct with the screw thread and it's an Allen socket screw.
