Sled has been sitting for about a month. Went to start it today and wouldn't fire up. Pulled a few times at first then primed once...kicked over but that was it. Did this before, so I pulled of primer line going to carb like I had to do before and it was dry; had to put finger over end to re-prime it and then fuel was shooting out. Pulled plugs and turned over 20 times, was flooded a little. What am I doing wrong here? Used to fire up fine when I first got it a few months ago! I read somewhere that someone said if the tank is below 1/4, sometimes the line doesn't pick up the fuel...where is fuel line going from tank to primer? Pulled more and still won't fire!! What's the best procedure to use so it doesn't flood and what are some things to check? Thanks
