My 1996 Summit 670 has been starting good when its cold but once warmed up its not starting. I rode it for the first time yesterday and it ripped down the trail. I shut it off when we came to a downhill overflow area and after pulling it about 200 times it wouldn't start. It has spark, I put new plugs in it, burned off the fuel in the cylinders with a lighter about 10 times. It would almost start when I held the throttle open like it was flooded but it wouldn't run. I eventually left it and my friend gave me a ride to the trail head. I have to go tow it home today with my polaris and wondering if there are any tips that you guys use to get the 670's started.
