I have a 2005 rt100 summit, been sitting all summer in garage with 1/4tank of gas. Put 5 gal of fresh premium in it and tried to start it. No luck, not even close. Took the pipe of and drained all the gas out of it and took out the injector fuses and turned over till gas quit puking out the y-pipe. Checked the spark, looked good, put new plugs in and tried again. First pull delivers a fireball, and not much on sencond pull and by then its flooded again.....repeat process! I have been pulling on this beast so much in the past couple days that something should have given in by now, either my arm or the sled. Any one got any ideas?????????
