Hey guys I just picked my my first gran torino after owner an LTD for years.The car is not currently running because Im guessing the car needed a carb rebuild.So i rebuilt the carb,set the needles all the way in until the springs were fully compressed and then 2 turns out is that correct?

Also i need to find a way to set base timing,I turned the engine until i was on compression stroke and then I put the crank on 10* BTDC is this correct?

After I did that should I drop the Distributor and have the rotor pointing at 1st Cylinder on the distributor cap?


If this is not correct let me know.

that will get you close, then set it with a light.

this also applies to your 400
 
 
'back when' I was taught a trick, it involves a strip of paper in the points, you twist on the rotor to hold the advance full then slowly rotate the dizzy body(I forget which direction) until the points release the paper strip... snug down dizzy clamp bolt
 
but it won't work with Pertronix installed, and I have no idea if the Pertronics will light a test light as the armature passes by the stator... so you're probably on the right track with the plan up above
 
dizzy housing Counter-Clockwise is Retard, Clockwise is Advance
 
let us know if you need exact factory timing specs

" ...  use your crank bolt and breaker bar to slowly turn the engine over until you get near say 30-40 degrees BTDC. Stop, TURN ON THE IGNITION, hook up your timing light, use a pal's hand or painter's tape to hold the light's trigger down. Advance the crank bolt until the light flashes. No flash + you're 180 degrees out. Fix and try again. If it flashes, your on track but note where it flashed!
Try it again (remember it will take another 2 revolutions) and see where it flashes at say 10 BTDC, 15, 20, whatever. Turn the ditzy housing until you get that light to flash exactly where you want it (I'll say 10 BTDC) and lock that puppy down. Prime your fuel system last and be sure fuel is right at the carb's shooters or EFI's injector tips. Hit the key and that puppy should fire right up! "

Update:Still no Luck

FUEL
*Float level is set right,doesn't overfill 
*Jets are spraying
*Fuel Pump is good
*Gas should be fresh put 91 octane in it
SO FUEL DELIVERY IS GOOD -although there is a small leak from the butterfly shaft but not big.

IGNITION
*A25 Autolite Spark plugs-Just put them in the motor out of the box,looks like they are gapped at about 45-50
*Pertronix Ignition replacing the points-Black wire to - on coil and Red wire to + on coil with switched ignition to it.I checked for Spark with a duralast coil and it was yellow so I replaced the coil with  PERTRONIX FLAME THROWER as recommended,but I havent checked spark color after I installed it.

TIMING
*I plugged the #1 spark plug hole with a paper towl and turned the motor clockwise by hand until the towel popped off and then I continued clockwise until i reached the 0* TDC on the pointer.(Should the Piston be slightly before it reaches the very top or slightly after it reaches the top?)



*With the Pointer on 0 degrees should the rotor be slightly before it hits the #1 plug on the Distributor cap ?,right on? or after it?

Im doing this by myself as I dont have a helper so Im just trying to do my best,your help is greatly appreciated.

with the pointer on zero  the rotor should be just a shad past the #1 terminal, as the spark should've occurred before zero. the rotor should be dead on at around 10* BTDC
 
but here's the thing... the rotor doesn't tell the coil to fire the plug, the primary trigger device does, in this case it's the Pertronix unit
 
see how the metal on the end of the rotor is wide rather than pointy?
 
that's to compensate for rotor phase (Yes I understand some people don't believe in Rotor Phase but that's why the rotor can't be pointy)
 
as long as the metal of the rotor has the terminal covered at around 10* BTDC you're good. 2nd criteria is that the advance can is centered in it's 'free sweep area', or as close to straight forward as possible favoring pointing toward the drivers side (US)
 
is it possible that the engine is flooded?
 
to start a flooded engine you either
 
a) take out the plugs, crank the engine a bit & wait for it to dry out then replace the plugs after gapping them to i's say around .040" for your set up there
 
or
 
b) you can crank the engine with your foot pegged to the floor holding the carb wide open to allow air into the engine to dry it out & hopefully find an air/fuel mixture that will fire & get the engine running. it's important to hold your foot down & not let it up or you'll be pumping more fuel in instead of air. when the engine starts coming to life don't let off the gas, it still needs air! don't let off the gas pedal until you think the engine is gonna blow sky high. it needs to rev & clear out
 
either method requires that the choke is not closed, you may need to prop it wide open with a tool of some sort that can not slide through the carb & down the manifold
 
but first I'd check for spark

Rockatansky-You took the win Thank you Sir

It played out exactly as you instructed down to the step on the pedal to make it suck air,it was not flooded,but i pumped the gas alot and then held the pedal down while cranking,timing was dead on and everything is good,car came to life and running fine,I will get a timing light and play with it,but at least its running.

Clap so it wasn't flooded, it just needed the gas into the manifold and cylinders initially, guess i overlooked that, makes sense now since it had been sitting and you cleaned the carb, it hadn't got any fuel in there in a while. glad you got it going! Clap
