OK, I give up - what is sea foam, and why were you pouring it into your
engine?

sea foam cleans out all the carb dirt inside the engine. it works i have
done this to my hondas and it runs like a champ, idles great.
i pour it in the vacuum so it can suck it throughly to the engine, this will
make alot of smokes coming out of the exhaust.

updates! the car starts but it sputter i have to hold on to the gas
and the choke to keep it alive, it sounds like too much fuel going in
or something. i open and checked both spark plug one of them was all
black and dry, does this mean no fuel is going in? or bad sparks?

There are three things to make a gas engine go: Gas, Spark, and twist(Turning engine) Pouring something into the vacuum line may have affected your vacuum advance to the points, but you should keep to basics here. Unplug a spark plug and check if your coil works by clicking the points with your screwdriver or finger while holding the spark plug wire 1/8" away from a good ground like the valve cover. Fat blue plus a biting sensational shock are good signs.
Spark is caused by three things: Points, condensor, coil: I check the capacitor by replacement. Points can be filed and honed a few times before replacing but in the end you can replace those too.  Motorcycle coils can sometimes be used if yours went bad.
Newer cars with fuel injection or oxygen sensors  have computers you must defy, but that isn't a problem here.
