They do look like dandies. I was interested to note, on the pic I pulled up, that the ends were ground to a point, as opposed to the rounded ends I sort of try to achieve. I guess something like a point would be appropriate. The 'sharp' point would always be held away from the wall of the tunnel. It would be the edges of the 'reamer' that would need to be relieved. Or so I think.George Ryals wrote:Wire and guitar strings can be made to work, but the Cadillac of carb jet cleaning is a set of Carb jet reamers: google it.
To me the term 'reamer' is a bit disturbing, as it would seem to imply removing material. I think of my guitar string 'reamers' more as 'pushers' simply disturbing crud that is softer than the surrounding soft zinc or zinc like metal. Once disturbed cleaning fluid can flow and melt the rest of the curd away.
As an aside I shudder at carb cleaners where you dunk the carb into a nasty broth for a period of time. I'm sure there are warnings on the label saying not to leave the carb immersed for an extended period of time. I have in my possession a set of 32mm flat top Bings with a plastic side plate. Evidently the carbs were immersed in such a cleaner so long that the plastic started to melt. As I recall the carbs came from a parts R80/7 that I acquired that shows lots of signs of abuse, or perhaps more accurately, idiocy.
