A vacuum hose brokegoing into carb. cut some exses off car started but stalled again. got a new vacuum hose on it but now the car turns over but wont start?
Re: A vacuum hose brokegoing into carb. cut some exses...
Possible vapor lock, try using some starter fluid, spray just a touch in carb. Another thing, is keep gas pedal to floor, and trying to start. Do not pump pedal, just keep to floor as you crank over motor.

Find the purge valve (pictured below) by tracing vacuum hoses that are connected to the intake manifold. It will be connected to one of those hoses. Might be on the firewall. If you don't find it, maybe the hose is disconnected from the manifold. Look for an open vacuum port on the manifold that SHOULD connect to the purge valve.
sure the only vac item that really matters is the ign vac advance , but engine should start and idle on "base" timing it just wont have any power to speak of without advance of timing
When does it stall? Give me some more details. But in the mean time Im gonna guess vacuum leak. Turn the car on and spray carb cleaner at the vacuum hoses. If you hear the engine wind up you know there is a vacuum leak in that spot. For your engine to stall and take a lot of gas its gotta be a big vacuum leak. But it might not even be a vacuum leak but its something to check into. It would be a cheap and easy fix if it is just a leak! Give me some more details if its not a vacuum leak. Good luck!
Sounds like you have a either a vacuum leak or a cracked fuel line allowing extra air to be sucked into the carb fuel mixture. Make sure all small to medium sized hoses are well attached to their fittings and do not have any cracks in them.
It could a fuel fillter But it could also by a vacuume hose leak . Get a can of carb cleaner, start car spray around vac hoses if the car starst to stall check the hoses you were spraying around
You probably have vacuum leaks somewhere. Be sure your base gasket is tight, and all your hoses are tight and not cracked. Use a length of fuel hose held to your ear with the engine running, and listen for a hissing.
On older, carbureted engines, cold stalling (and hard starting) is most
often due to an automatic choke that is sticking, misadjusted or
broken. Cleaning the choke mechanism with aerosol carburetor cleaner
may free up the choke allowing it to work properly again. If the choke
housing as an electrical heating element, the element may not be
receiving voltage when the key is on, or the element may have burned
out (check resistance with an ohmmeter).
Other causes of stalling with a carburetor include an idle speed
adjustment screw that is set too low (turn screw to increase idle speed
rpm). The engine may stall if the idle fuel mixture screw(s) are not
adjusted correctly or the idle mixture port(s) are dirty or clogged
with fuel varnish deposits (clean the carburetor and readjust the idle
mixture screws for smoothest idle). Stalling can also occur is there
are vacuum leaks in the carburetor, under the carburetor (bad base
gasket), or any vacuum hose connections to the carburetor or intake
manifold
