Just did 2 to 4 bbl swap car starts wont stay running please help

the easiest way to go would be to just set the total timing (initial + the mechanical advanced with the vacuum advance disconnected) to 34 degrees while someone helps you keep the engine RPM around 3000 (or anything over that). It doesn't have to be precise, you just want to make sure the mechanical advance is all the way in.

Do you have a dial-back timing light? If not it would probably be easiest to buy some timing tape to degree the dampener since the stock timing tab doesn't show anything past 10 or 15 degrees BTDC.

since you don't have a tach, just have someone ref the engine until all the mechanical advance in the distributor is in, then using a timing light and set the timing to 34 degrees while keeping the engine RPM's high.

If you now let the engine come back to idle (750 rpm) the initial timing will most likely be between 10 - 15 degrees. Just make sure when setting the timing that you have the vacuum advance to the distributor disconnected and the port on the carb blocked off.
