JUST BOUGHT A '73 XLCH THAT SAT FOR 2 YEARS BECAUSE THE OLD MAN THAT OWNED IT COULDN'T KICK START IT ANYMORE. IT STARTS RIGHT UP BY PUSH STARTING IT, BUT KICKING IT IS ANOTHER STORY. IT'S GETTING FIRE...
You probably need to adjust your valves. Ironhead Sportsters are equipped with solid lifters and must be adjusted with zero backlash. If one of the pushrods is adjusted just a bit tight and holds a valve open even slightly, the bike is almost impossible to start with the kickstarter.
To adjust the valves, the bike must be stone cold. Take the spark plugs out, raise the rear wheel of the ground, and put the transmission in fourth gear. Turn the engine over by bumping the rear wheel in the normal direction of rotation. Bring the piston of one of the cylinders up to top dead center on the Compression stroke. Pop the pushrod tube covers and check the pushrods. You should be able to spin both pushrods with your fingers. If not, adjust the pushrod so taht it's tight. Then back it off to where you can just spin it with your fingers. Keep in mind that on a Sportster, it's better to have the pushrods slightly loose than tight. Once you get that cylinder's pushrods adjusted, do the same thing with the other cylinder.
Now, once you get this done, starting your bike is simply a matter of figuring what works with it. I've always said that kickstarting a Harley, especially a Sportster, is a ritual. Some bikes like for you to milk the throttle twice, kick the engine through twice with the choke on and ignition off, then turn on the ignition and kick it. Other bikes seem to want only one milk of the throttle, one kick with the ignition off, and then kick it. Each bike seems to have it's own particular ritual that you must figure out to get reliable starting. I'd try milk the throttle once, put the choke on, kick it through with the ignition off once, then turn the ignition on and kick. If the bike spits back through the carb, you need to start all over again. If you get the engine flooded, hold the throttle wide open and kick until it fires.
One other thing about a Sportster. Did the old man you bought it from have a limp in his right leg? A Sportster is notorious for "slipping through" when you try to start it. The result is that all your weight comes down on your knee without any resistance. The result is your knee tries to bend backwards, the way it wasn't designed to do. This can tear ligaments and cartilage in the knee and it even has it's own name, "Sportster Knee". Be careful.
