I was cruising pretty fast and I noticed some noise and when I turned around I saw smoke/Steam come out of the motor engine cover And notice the motor not peeing And then it killed, after Cooling it started backup But it had very poor acceleration, but I did get back up to the same speed And started peeing Maybe it was something clogged The intake at the moment, but now I have poor acceleration or it might even kill If I give it too much gas too fast , but I can get back up to fast speed as before, I took apart the carburetor and clean it, and still the same poor acceleration, I don't know what the compression is supposed to be, So I did a test and got a little over 95 PSI, I don't see any signs of exterior blown head gasket, Maybe piston rings or electrical part that got overheated?
