I have a 2006 rmk 600 .I tried starting it on Friday . It was hard to pull . Sometimes it is hard to pull at first , I pulled it about 5 times did not start . Fuel started pouring out the belly pan. I had it running great about 3 weeks ago. I usually take it to dealer for repairs . Is it possible that engine filled with fuel that's why it was hard to pull . It did loosen enough to pull . Any suggestions on where to start , Had my wife daughter and granddaughter didn't want to wrench all weekend at camp. We had 15 inchs of snow on wed . Saturday night we got another 15 inchs . So with 30 inchs snow on the ground of course my sled acts up.
