As I recall, you ended up using the idle air jets to adjust idle mixture/speed. That right?

Well, the main problem I am having is it just blows a lot of smoke. It didn't do that before the carbs.
I start it up, poof. Lots of smoke.
I decelerate and poof. Tons of smoke following me up to the light. It's kind of embarrassing.
It didn't do any of that before the carbs. I keep thinking my rings are bad and the carbs are sucking so much more air that that is the reason it is pushing so much out my tailpipe. That's just a guess.
I don't know.
Could be the valves?
Yeah I tried to add more air by opening up the air jets a bit but that didn't really do anything so I put them back.
Basically, I just put the carbs on the way they were shipped. The specs listed above are the way they came.
They are perfectly balanced at idle and at a higher RPM. I have checked all that.
My plugs are new and gapped at 60. NGK BP5es, I wanted a bigger spark to help ignite more fuel.
Im out about 3 turns on the screws. PMO says that if you have to go 3 1/2 out it means you probably need bigger idle jets, but I think I am cool with that. I'd say my idle jets are fine.
I think mains are small enough already at 135.
What would putting a larger air corrector in do? Add more air and help vaporize the fuel for better burning?
If I need bigger air correctors, are they the standard Weber ones that I could buy at any speed shop. Or are they special only available from PMO.
There is one thing about the carbs that I find strange though.
When I put the synchrometer on them, they are all balanced perfectly but cylinder #3 has to have the screw almost completely out in order to synch.
The others are all in range without even having to adjust the screw very much.
#3 is getting spark, I pulled the wire and checked that.
It runs and runs pretty good. It just smokes like some old jalopy.
It's embarrassing.
