carburator jets, accuracy of carburator jets. Options

[ME733]

(IMG:style_emoticons/default/popcorn[1].gif) well gang just reciently there have been some posts about carburator jets, air correction jets,jet carrier, and their location, and how to read them. My question is this. For those who have measured /verified /checked the accuracy of Jets, (both air and mains) who would you recommend , and who would you purchase them from?. I ask the question because some "new" jets I have collected are a little off. examples, 120,s were 130,s, 125,s were 135,s, 130,s were 145,s...etc., it,s easy enough to drill out a small jet and make it larger.(with jet drills) but this doesn't work in reverse naturally. So who would you recommend for new accurate Jets! or other accurately made carburator parts. (IMG:style_emoticons/default/popcorn[1].gif)

Quibbles. Certainly you could do better with a lathe, but not enough better to matter. Have you measured those jets you're buying new to compare? That was the original complaint, variability among purchased jets from their marked size. In any case I said solder and drill until you have it jetted correctly, then, if you prefer, replace with new jets in the correct size. I've never found the need to put in new myself, and think you're just as well off or better with the jet reamers/drill index.

People who jet each barrel individually exist of course, just nobody I know. People who used to spent that much time on the dyno were serious racers who these days are all running fuel injection.

Your experience may differ, and that's fine. The important point is to know that there are different ways to do things, judge for yourself what's best for your case, and then do as you like.
