i was driving in these gravel pits the other day and i had to get off to turn it around and my motor died. i thought it was out of gas so i put it on reserve and then tryed to start it and the motor was making a clunking noise. i put it on my truck and drove back to my house and tryed to start it again and it didnt make the clunking noise but it felt like there was not much pressure coming out of the exhaust tip. what could this be? blowen motor?

 

Do a Compression check first thing, you can buy the tester for under $20 at just about any auto parts store.
