i need a crash coarse in carbs
one of my friends has a 70's T-bird that has been sitting forever, about 7 years. body is in perfect condition(been garaged this whole time). just last year her ex husband pulled the motor and took it to a shop and they has all new bearings put in the block and had it honed, crank turned and re ringed the pistons. then he took the motor back, put it all back together(cam, heads, intake blah blah blah) he couldnt get it running before my friend and him got divorced.
now she wants to get rid of the car so she has her spot back in the garage. she said if i can get it running and drive it out of there i can have it. not that i particularly want it, but i can sell it
i dont have any question that i can get it running but how do you tune a carb? anyone have a good tech article that explains for newbs or can you give me a quick explanations? im sure i can figure it out easily, just need a push in the right direction.
and pardon my title...wrong "course"

on the underside of the carb there should be screws that adjust the jets inside the carb.. depending on if its a 2 barrel or 4 and how many jets will determine how many screws.. also if it wont start check the choke on the car its the flap over the top of the carb. especially if it is a electric one.. i would take some carb cleaner and they make a starter fluid to spray in to help it start.. most likely tho its the jets are not getting enough fuel in or the choke flap isnt moving to allow the air to get in.. hope this helps.. if all else fails just buy a new carb

im not sure yet why it doesnt start but she says it does crank. i havent gotten a chance play with it yet but i saw the machine shop receipts. i just figured im going to have to set the carb once i get it running. how do you "tune" it with the jets?

Buy this book
http://autosupermart.com/store/shop/hpb00052.html
only 210 pages or so, and you'll come out the other end a much smarter individuial.
Why do you say the carb is an issue?
If its all gummed up douse it with carb cleaner.
What model carb is it?
What are the no start symptoms?

im not suspecting the carb, im just assuming it will have to be set once i get it running. my guess is the guy that put it together didnt know how to stab the dizzy correctly because she says it'll crank and pop a few times but never runs.

im calling her now to ask what kind of carb it is.
i plan on restabbing the dizzy and TDC and checking fire order, check plugs and introduce my own fuel to make sure i can get it to fire. and if it doesnt i'll go through the troubleshooting steps. the mechanics of getting it running are no problems. i just have never messed with a carb before.
