hard starting engine, is this after it sits for weeks ? the flex line might have a leak ,,, that leaks air in letting the fuel retrun to the tank and loose its prime, ? ot the fitting on the intake side of fuel pump how old is the fuel pump, this hard start all of a sudden ? do you smell gas after you shut off the engine , you carburetor could have a drip. leaking gas out, draining the bowl put a paper towel under the card bowl and see if it has any signs of gas, how is the fuel lines under the car from cowl to the tank how much fuel in the tank, more info would help my 2 cents, 37Ragtopman

Are you sure that you have a functioning ignition system that is providing spark to the plugs? An easy way to determine this is to spray some starter fluid into the air cleaner before trying to start the engine. If the engine does not at least try to fire the plugs, your ignition system is at fault.

In order to solve your problem you need to do some diagnosis and describe your symptoms in more detail. Some of the causes of hard starting are: lack of fuel, too much fuel, weak spark or spark at the wrong time and improper starting technique. To check for fuel problems, before trying to start the engine remove the air cleaner and operate the accelerator linkage while looking down the throat of the carb. You should see two streams of fuel from the accelerator jets. If you do not see them, you have a lack of fuel problem. Look around the base of the carburetor fuel bowl for signs of leaking fuel. After shutting down the engine look down the throat of the carburetor to see if there is still fuel dripping down into the engine. Either of these is a sign of too much fuel. If neither of these conditions are present, you may have a spark problem. Start the engine and let it idle. Hold one of the ends of a plug wire near a head nut and observe the spark. It should be blue in color and about 1/2" long. An orange color indicates a weak spark. Describe your symptoms in detail: hard starting when cold hard starting when hot hard starting all of the time do you use the choke do you pump the gas pedal do you hold the gas pedal to the floor do you hold the gas pedal partially down does the engine try to start, but doesn't catch what you do to finally get it to start I hope that this helps you.
