my 67 225 dart is dying on me was tooling around today had been stop and go at stores around town for 2 hr when sitting at a light she died has gas, spark, not overheated, let sit for 15 min and started ran for 5 then died again, plugs are a little carbon fouled like it is running rich. not sure where to go any help is appreciated since this is my daily ride to be used as I fix up

 

could be vapor lock, pluged fuel line, (partly pluged)

 

thats possible the lines are old and I just finished using the old gas that was in the tank had sat for about 3 months

 

how's your carburetor float? needle? the needles can get stuck, causing flood...i went through this one last month. beware a carb fire!

carb issues can also cause plug fouling. also, fouled plugs can cause the stalling.

let her sit for an hour or so then manually pump the accelerator from the engine, watch your carb, check for gas leaks around the bowl gasket. one thing we've done is to whack the carb bowl with a hammer, if the needle is stuck this often frees it up and she'll start again. do not start if there is gas leakage on the exhaust manifold! rinse it off with water or let it evaporate.

are you having any 'surges?' like when you're driving, your engine drops out then lunges?

 

Well, theres your problem...

Gas doesn't last as long as it used to now with all the additives they put in...

Throw some FRESH gas in and a set of plugs and you'll be set.

 

got good gas, plugs, and changed fuel line, and filter, got valves, timing, and points adjusted feels a lot better

 

Sounds like vapor lock to me. If it happens again, I'd try to reroute the fuel lines away from any heat sources.

 

metal -

The symptoms really sound like vapor lock, but you said you have gas, I assume yo meant that you could see gas squirting from the carb, right?

Humm... how did the points look???

Regarding the old gas and plugs, if you have to let it sit for that long, throw some Sta-bil in the tank.

The make a phenoseal (?) type spacer that disipates the heat from between the intake and carb to keep that from happening. Depending on what RPM range your motor is built for/works in, you can get different spacers ranging from 1/2" to 2" and either single wide open hole design or a 4 hole design.
