Nice work! I've not had a serious enough carb to play with air bleeds.... nice to be learning along with you.

There's always something new to learn. -
good stuff.
even at 950hp.
so to increase a stable bridge of low to high and stabilize, drop the main jet size and increase air bleed.
something funny with carbs.
I have been tinkering with ten times less the horsepower and a fifth of the displacement.
the bleeds and jet are the same for 108 all the way to 250ci.6 to 4 cylinder .
proves internal combustion has a big pause, and should think of individual cylinders..what the natural flow is etc. the rest is overlap of how many you might have.

There were a few cars on DW last year that the backs were sooty black from running rich on the highway. Talked to one of them at a gas station and they were getting awful mileage. I don't want to be one of those guys! HahaLife is short. Be a do'er and not a shoulda done'er.

Be happy they have removable Air Bleeds now, back in the day when I was doing this stuff we used drill bits and different sized wire and hoped we got it right...........Originally posted by BBR View PostLearning this stuff is something I always wanted do, but never needed to. I'm diggin this stuff.

When they don't have removable bleeds you drill and tap the body for brass set screws and drill those. That carb must be way undersized to be able to pull enough fuel with those 45,s in there. Most times you end up with 28-32. The 950 hp actually flows less than the 850.Last edited by slimbo5; June 20, 2012, 04:19 PM."Friends don't let friends run the daily driver class,"

Yep. That was one of those things I learned *after* I bought the carb. HahaLife is short. Be a do'er and not a shoulda done'er.

Not a carb expert but I was also thinking air bleeds to sneak up on the mixture. They're in parallel circuit to the main jet. It the carb is too small, it pulls too much vacuum through the fuel circuit and over powers it. Increase the air bleed and you draw at some of that vacuum away from the main jet leaning it out a bit as I understand it.
Now dieselgeek would have you putting EFI on it.TomOverdrive is overrated
