If the engine is having trouble starting there is a chance that the hole in the gas cap has become clogged (If your engine has this feature).To check this just lightly screw on the cap, and see if the engine starts. If you need to just run a small gauge wire through the hole to clean it out. When there is only a trickle of gas coming out of the main line you should check the gas tanks filter, which can sometimes be cleaned a little with a light brush. If the gas is still coming out slowly try cleaning the lines this can be done by running a pipe cleaner or something similar through the line until the pipe cleaner comes out clean. Some engines also have push primer which helps create the right air fuel mix for the engine. It should be free of cuts and the air hole should be open.

I would also like to add that another problem that makes the engine hard to start or not want to run at all is a worn out carburetor bowl gasket. It will drain your gas tank quickly too as gas will evaporate out of the carb. Sometimes gunk can help seal up an aging gasket to the point where the gasket will not seal once cleaned. To test for this, with the engine COLD and OFF (if it's hot/warmed up a fire may result), connect the carb to the gas tank and allow the bowl to fill. Tilt the engine slightly. If gas spills out of the carb bowl, replace the gasket.
