Your wasting your time buying 1/16" bits in anything less than 10 pack,
Buy in bulk on-line for a better deal on better quality dills

This is right out of my a&p book.
I use stainless or Monel

Texasstar said:So by changing out the needle jet we are trying to lean out the fuel mixture 1/2-3/4 throttle to match the lean at WOT??? Then we can increase the main jet and bring zen to the carb???

we are the fortunate ones lol thank you we are hoping our lucky numbers are 12-12-12teazer said:Correct. We are in search of harmony and peace. The correct height of spray tube brings asymmetric balance to the fuel curve resulting in harmonious combustion. Did I tell you I write for Fortune Cooking dot com? LOL
Taller spray bar is closer to the center of the carb where flow is faster and therefore it allows more fuel to flow because essentially the signal is stronger. But as revs rise, that taller nozzle will tend to act disproportionately stronger than a shorter one and will make the mixture richer as revs rise - at the same throttle opening (WOT in this case) and keeping flow the same at lower engine speeds.
The air jet has a similar effect on flows.
Changing float levels and needle jet diameter (or needle root diameter) change flow at all engine speeds and while not proportionately, not as effectively to tip the fuel curve. But just raising the fuel level (lower float height) may be enough to lift the whole curve sufficiently to hit that home run.

Teazer that would be great! I will pm you!teazer said:Most slide carbs from that era are the same diameter and same bottom end but different heights.
I measured
CB160-175 10mm OAL
CB77 10mm
CB750 K0 12mm
I have 1.0mm air jets available (stock is 1.5mm according to my notes) and a couple of those 2.6 * 3.6 CB750 12mm jets if you need them.
for everyone's info I did this wrong...the wire needs to encompass the boltTexasstar said:Correct? Edit: this is the wrong way to safety wire
