18 thousanths!

[Anonymous]

I just found out from Earl that the opening in the float bowl should be 18 thousanths of an inch. That about 1/55 of an inch.

Should I meeter the straw, or try to fix the bowls? I have seen other cv carbs with the straw plugged. I didn't know why till now, but those plugs were probably meetered.

If your wondering what the heck I'm talking about I posted earlier about drilling my choke circuit in the bowls to 5/64. OOPS!

Re: 18 thousanths!

I have a stainless steel bristle from a brush that I use to "ream" the choke tubes if theyre blocked. The bristle is a close fit in the tube. The bristle measured 18 thou with a micrometer. Thats not quite the same thing as saying the opening should be 18 thousandths. Its probably close, but........

I got a set of diesel engine injector nozzle cleaners to use for this. They have the diameter marked.

Or welding torch tip cleaners will also work, and they are "sized"

DON"T use welding tip cleaners !!!!! They will make the hole oversized !!!! They are actually a FILE !!
