So I'm back with more of my engine troubles. Recently the 305 in my elky has been running really rough. Most mornings it would start up fine and run like a top and then some time later in the day it would start running rough. I assumed it was just running rich but it goes back and forth between running normal to running poorly. When I stop at lights the engine stays on but it goes up and down between 600-400 rpm and when I hit the gas to leave the light it doesn't respond. It goes to about 1000 rpm and stays there for a bit before taking off. Recently as well it hasn't been starting how it should either. I push the peddle down once and it crank it. It sounds like it's going to start but then it just cranks and no amount of pressing the gas will even make it respond. I've had to resort to using starter fluid to get it started a few times. So please help!
