well i went to go and start my car and it stalls after like 30 seconds or earlier. I have it on TDC and the Rotor is pointing to the #1 cylinder on cap. Well i thought i capped everything and i guess i didnt. Well then i did then i saw i had oil pouring out of the back of the intake manifold. Could that be causing my car to stall?? So after that i sealed the back of the intake and all. I havent tried after that but then again my starter cracked in half and still didnt get a new one. But im just wondering if that would make my car stall and if not what else could it be..

thanks

i swapped from a 305 tbi to a 350 carb'd

 

if it started and then stalls out....might be like a sticking chock...or you have a vacuum leak somewhere...

 

ok well the choke does seem like it sticks because it only opens alittle then stops if that is the case what is the best way to fix that without buying a new carb thanks

 

When the car is started cold, the choke should be completely shut until the engine starts. When it starts, the vacuum break or choke pull off should open the choke butterfly slightly. As the engine continues to run, the choke should slowly open up. Sounds like yours is operating normally as far as the choke pull-off is concerned, but you didn't have it running long enough to fully open the choke.

Oil leaking from the back of the manifold will not cause the engine to stall. The bigger question is why it was leaking from the back of the manifold - had you just replace the intake gaskets? If so, did you get them installed correctly? If the manifold isn't sitting down properly on the heads, that could be the cause of a big vacuum leak, and may be why it was leaking from the back of the manifold.

Also, "TDC" comes around twice in every full combustion cycle. What is important is having the #1 cylinder at TDC in the compression stroke.

More information needed about what was going on before this condition developed.

 

i cant have it runing any longer because it shuts off by itself everytime i start it after like 15-30 seconds i have no control of it turning off it does it by itself. im thinking about getting rid of it because it just stresses me out.

 

don't give up....just have to find what's wrong with it....so it runs for 15-30 seconds then dies.....are you just letting it idle and then dies....or are you pumping the gas and it dies....maybe your not getting enough fuel up there....bad fuel pump maybe??? But the vacuum leak idea could be it too....when you go to fix intake manifolds...buy new ones...and make sure you put black rtv silicon on front and back center sections of block (inbetween heads) to seal those...don't reuse intake gaskets......keep trying..you'll find it eventually...keep asking questions and posting info and you'll find it...

 

well i did reseal the intake but i still need a starter but then again before when i had it started it would not want to idle if i let it go under 1000 rpm it would stall im thinking also i need to bump up my fpr because i didnt even touch or mess with that i just got it and put it in without setting it. maybe that could be the problem as well like you said not enough fuel? or maybe my throttle bracket has to much slack?

 

ok well i got the new starter in and it still does it. It stalls after like 10-15 seconds but when i goto rev it and hit the gas to the floor it wants to stall any more options on what to do? thanks

 

What carb and fuel pump are you running ?

 

i have a holley 600cfm and the electric fuel pump(stock)

 

may be a dumb question on my end, but are you running a return style fuel pressure regulator? what do you have for pressure at the regulator?

 

yes iam using the mallory 4309 FPR and its set at 6psi

 

open the front flaps all the way so they cant close. auto chokes suck!

what made your starter bust? if your starter breaks again you may have to buy an old school cast starter. i had to get one for my roc because of high compression! i broke seven aluminum starters before i got it right. my starter fits a 68 impala.

 

do you mean the flap on the horn of the carb push it all the way down so it cant close?

 

You could have gotten a high torque mini starter the first time and you wouldnt have wasted all that money.

 

i mean the flap over your front barrells on top of the carb. if it closes your car will sputter and smoke black smoke before it stalls.

 

i tried the mini starter but it wouldnt fit because of my exhaust. i was able to find a cast metal starter for 130 bucks

 

ok i will give it a try and come back thanks

 

the flap wont stay open idk how to keep it open.
