half speed engine plz help

I was riding it down my road (my 200s). i ran out of gas so i put it on reserve and as soo as i did that it bogged way down and went like half speed. When i shut it off and let it cool i tried to start it back up and it wouldnt start . it wouldnt even pop start. i think it might be a blown head gasket. could u plz reply if u know wats wrong

Did you put gas in it? Reserve travels through a different tube, which may be clogged. Fill it back up and switch from reserve back to regular poition.

if the head gasket is blown, it will try to start, then want to sputter and hiss, and die. i think that the problem is that would may want to unscrew the screw at the bottom of the carb and let gas come out. sometimes and air buble comes threw the gas line and gets caught

I would try cleaning out the exhaust.

also the reserve is going to suck from the bottom of the tank so you might have got some trash. check the fuel filter. if you dont have one you might of sucked trash into your carb.
