(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)

Hmmm... That's how I've done it for about four decades now, on my own and on customer's cars. Good to find out it doesn't work. Thanks.
Still scratching my head though. I'm aware of no way to get a more accurate hole than with a drill index. If you use the same drill in each hole how could they end up being different? And if you can't solder then of course the best advice is "don't". The wide band tells you how the MOTOR is running, rich or lean, in different running situations, so it has to be in merged exhaust flow. You jet each throat the same, so the whole engine is in balance. You could jet each barrel individually, I suppose, but I don't know anyone who does, or why they would. |
