I’m in the process of rebuilding a set of BS38 carbs. The needle jets in the carbs were in pretty bad shape so I was looking to buy new ones. I have since posted a request to buy a set in the classified section.
If I’m not successful getting a “new” set, I may try to reuse the old ones. Before I do this I want to make sure that the ones I have are actually Z8 needle jets.
I measured the hole diameters in the sides of the jet and the larger holes are .030” and the smaller are .024”. Was wondering if anyone had a set that they could measure for me, to confirm I have the correct jet. Unfortunately there are no markings on my jets. To measure the diameter of the holes I used a set of number drills, using the shank of the drill as a measuring tool (didn’t want to use the business end of the drill bit for fear of enlarging the hole).
On another note, does anyone have a go to method for removing a petrified oring in the needle jet groove. It’s as hard as the brass jet and removal with a sharp dental tool won’t touch it. Though maybe I could soak it in some chemical to soften it up.
Any help would be appreciated. Picture for attention.
