Guys,

Well I need to run something past the resident experts here. 
1. I have a 1956 272, with 3x2 Edelbrock 553 Intake, Ford 94's.  The motor starts and idles great.  Once I begin to accelerate the motor bogs down, almost dies, I lift off the gas a little then it starts again strong and then all three carbs can open and it runs fine.  All the carbs have just been professionally rebuilt with new gaskets, so I don't think it is the carbs (or setup).
2. I am running a Petronix 2, with a reman Cardon Distributor 57+ style.
3. My vacuum to the distributor is coming off of a tee from the intake, one going to the distributor the other going to the trans (TH350).
I am going to buy a timing gun as well as a vacuum tester, to set it properly because of now I am only in the ball park.  I think I have the idle process down, where you pull the vacuum and set at 8-12 degrees depending on motor, then reconnect and run up to 2.5k rpms and set vacuum advance setting. My question is how do you change that setting (Vacuum advance)?  I have read where you can stick an allen key in the canister, but I have no hex to adjust in my distributor, and I have read where you add Mr. Gasket springs (925D I think???), but I see no springs in my distributor.

Also, should I be pulling vacuum from the carb?  I do not see anywhere on my carbs where I would hook a line up to.

Sorry for the questions, but I want to get this thing dialed in proper.

Thanks,

Ryan
