2 1997 Arctic cat powder special exc 580sThe green one starts and runs great for a few minutes than looses fuel pressure and dies. I suspect it needs a new fuel pump. Only has 1900 miles The blue one starts and runs but bogs and dies with throttle. Seems to be flooding itself out.Both sleds are in good shape for their age.I am asking $1300 each or $2500 for the pair I have a parts snowmobile with a good motor I can throw in for the right price
