I have 2 crappy 34 tm's here. One is jb welded back together(runs fine) the other I got for 10 bucks and free shipping.

I see that 35mm hole saws sell for $7.00 lol where as a 36mm is about $50. The 35mm is 1 3/8"........A standard size for hole saws.......

Also the carb splits in half vertically when the bolts are removed, So I see I DO NOT have remove/press the brass needle guide in the center. It can remain intact while boring. Of course it will not be perfectly straight but much easier!

So in a nutshell I am convinced it is a simple thing to achieve. The issue will be sorting out The idle circuit problems from change in flow etc etc etc etc

If you guys could help me sort the needle and jetting/ fuel circuit stuff out keenly, I am ready to go.
Thanks

no offense, don't want to stir the pot, but i read you have access to a cnc, can make all kinds of fancy parts, read university text for fun, and your going to use a hole saw to bore out a carb??? 

now you could make these great parts i don't know never seen anything, not saying you don't,  but you don't use a hole saw to bore out a carb.  you should be smarter than that.  if you do that your gonna have more problems than jetting.  your reading the wrong text.
