Carbide 150cc
 

I have a Carbide 150cc buggy and when i start it it runs for a while then gas come's out of the exhaust and then the motor will not turn until i take out the spark plug out and turn it over to get the gas out of the plug. I bought a new carb cause I thought it was something wrong with it and it still does it. on the petcock is the hose with the filter goes on the bottom our the top. also there is a y connector that has some hose's going to the carb and exhaust boot
