I was using the 600 with a PT on it a few days ago and it stopped and I thought it was out of fuel so I packed things up. I went to put fuel in it this morning and I looked in and it wasn't out of fuel, still had fuel covering the tap. I put more fuel in it and it gave a couple of flutters but would not start. It has spark. I changed float needle, tried a couple of new plugs, tried a squirt of starter fluid, nothing, not a peep out of it. It has compression not excessive but it should run fine as it is. This one has me a little confused as it was working and starting perfectly before it stopped
