i've had my s2k for awhile now and it's always had this problem, but its just geting a little more niticable. every once in awhile it will take a little while to start. the battery is fully charged, and the engine turnsover fine, but it does not fire. it either takes a little more cranking it over or it floods itself. i've cleaned the plugs, replaced the plugs, checked for spark(had great spark), and it still does the same thing.

it usually come in waves when it does it. it will run fine for weeks, but sometime when i go to start it it will start hard, next time a little harder, and then after a couple times it won't start at all. the last time this happened, i leaked enough gas into the cylinders that when i took the plugs out and cranked it over to get all the gas out, you could hear it sloshing around my bet is on leaky injectors. anyone know how i could test that? or any other idea?

thanks
