Motorcraft Carb Swap done

I did the nutter bypass and just need to fine tune and finish taking various tubes and vac switches out. What other fine tunig hints are there out there? Do I really need to do the nutter bypass?

It just seems to be smoking a little as well as idling fine and then just dies. What do I need to do?

When it dies does it choke and die, shut right off, how about starting it again?

Is the choke functioning properly?
Did you set the mixture?
Did you rebuild the carb? If you didn't perhaps it needs a rebuild. If you did are you sure you put it together correctly?
Perhaps the timeing needs to be ajusted.
Maybie you do need to disable the ECM, I don't think mine is disabled but I think it's the cause of a couple problems I'm having.

It goes to a real low idle then dies. The carb is rebuilt (Got it from the guy on ebay so it should be). It seems to run ok with some sputter at high rpm then if I let off gas it just dies.
I have it hooked to a vacuum gauge to adjust the fuel mixture screws. Is there a better way?
Having a hard time seeing the exact timing marks so I am kind of timing by Vac gauge/sound.
The choke seems to be working fine. Closed when cold then opens all the way when it warms up.

I am thinking it goes back to a timing issue. I am also thinking of redoing the wiring an NOT doing the nutter bypass. I have heard both ways are fine but still unsure about it.

Wife wants to drive it and I am losing my patience.

Mark your timing marks with a little white or yellow paint. They show up like lights under the timing light.

Yeah I am just having a hard time seeing the top of the tab to see what mark is what number. I think there is an old mark but not sure.

If you got the whole $250 setup from the guy on eBay ask him. He seems to know a lot about these carbs and can probably give you some insite. That's what you paid the extra money for isn't it? Ther service of having the carb rebuilt, all the parts put in one box, and help with the installation.
