I just bought a a 07 Hisun 700 for $600 from a friend, it starts right up, runs for about `10 minutes and quits. no fuel. spray gas into intake and away it goes,but only on the gas being sprayed in. let it sit another 10 minutes and it starts on its own ? fuel pump maybe? its vacuum operated? might try a small elec pump.its nice shape ,had this problem for long time. it has 800 kms on it.

 

Check the fuel tank vent for clogs. Common issue across we all ATVs

 

Also see if it has a plugged inline fuel filter.

 

thanks, will do. it sure looks similar to a Yamaha Rhino ?
