Here are two tips for trouble-shooting with gasoline fueled cars.

Item 1 -- If your car has the perennial trouble of hard-starting after several days of inaction, adjust the choke to more rich and also the idling jet screw to more rich; then to prevent the combustion from being overly rich when the engine is running smoothly, adjust the engine idling speed to compensate against the rich adjustment of the idling jet screw.

Item 2 -- If your car engine is starving for gas on the road so that finally it refuses to ignite because no fuel is getting to the carburetor and thence to the engine, almost always it is the gas filter being fouled up as to stop totally fuel from getting to the carburetor.
Look for the fuel filter -- it can be located behind and below the car battery; remove it from its two hoses, one input and one output, pour the content out of the input mouth, removing thereby impurities and water, then return the fuel filter exactly as it was before.
This happened to my son after filling up for the first time a full tank of XCS Petron gasoline which promises to clean the tank, the carburetor and the combustion chambers -- trouble is where does the filth go after the gas tank has been cleaned? Where else but to the fuel filter where it will obstruct the passage of fuel to the carburetor.
By the way, get a new fuel filter installed when you are out of the crisis.


Hope these tips help.
