Yes, its the same sled. I will be tearing into things soon, I need to find out why this piston failed before replacing it. The sled sat for over 4 years before I purchased it. What might happen to the motor if it sat with no attention for that long? The sled idled and started with 1-2 pulls(dead battery) the garage smoked to beat the band....hard to believe both cylinders were not getting oil.scumpman said:A failed pump would not deliver oil to both carbs.. might be good to change out the oil lines.. is this the same sled in your other post the 488f??
