Starting
 

Hey there guys New here. And trying too find out why my carter raptor 150cc won't start I have changed papcock on bottom of gas tank. Changed carburetor but still does want to start. When I spray gas into to carb it starts but stops after in burn the gas away Can anyone help pleas

Is the vacuum fuel pump pumping while cranking engine? Does the carburetor have fuel in the bowl?

Not sure about vacuum fuel pump. But I know carburetor has no fuel in bowl

Check and see if the fuel filter has gas in it. If the fuel filter is not stopped up then clean out the carburetor bowl. Should start right up.

The Carters originally come with vacuum fuel pump located at bottom of fuel tank. There are 2 lines going to the pump. One is vacuum coming off the intake the other is fuel line going to the carb. On the pump the bottom line will be vacuum the top fuel. Remove the fuel line from carb, crank engine and you should see fuel pulse from fuel line. If not remove filter. If still no fuel, pump is bad. If fuel is pumped than the problem is in the carb.

Get rid of the vacuum operated petcock and go with a manual one, and if u can 1/4 clear fuel line and a inline filter that way u can see if ur getting fuel and its a much better setup.
