i changed the plugs gaped at 030 put new fuel new bottom end oil, all was going good untill i put it in a old steel barell to try and see if it was runing ok. I got it going after a lot of pulling the water poured out of the back port water jet no problem, but as it ran for awhile it must have sucked up some rust and dirt, the water slowed to a trickle, so i brought it to the lake and tried it there, it ran perfect, but the water wasent coming out to fast , so i took the tube of inside the motor and blew it out, the water started flowing again, so i took it for a ride at full power, but i felt the top part of the leg and it was very hot to the touch is this ormal because it is were the exast port is coming out, or am i in trouble ?
