my chinese cougar 150cc wont stay running its been sitting up for a few years and some of the hoses are dry and falling apart i got it to start reciently but only if i spray carb cleaner in the intake and then it only runs for a couple seconds i think its not getting fuel any suggestions

 

The carb is dirty and needs to be cleaned.

 

still wont stay running and gas is pouring out of what i think is the overflow valve at the bottom of the carb

 

gas is pouring out of where? the carb itself back into the air filter? check your crankcase oil for gasoline contamination. if the needle seat/float assembly is stuck open, you're obviously flooding the engine. change the oil. pull the carb. if it won't idle, your pilot jet is still plugged. here's a video to follow that'll show you the orifices.

while you have it apart, double check and make sure the float assembly actuates the valve. that'll save you some headaches. good luck

 

mine has three holes where the jets are i took the jets out and cleaned them couldnt get the other one off but i did spray carb cleaner in it so it should be clean now i reinstalled itand it starts but it won t run for long and when it kills it wont start up unless i let it set for a min then it will start and idle for about a min if i give it gas it dies thanks for your help

 

so when you pulled the jets, you could see daylight through the orifices and down the jet on the inside, right?
how does the float assembly act when you triggered it with your finger? did it act like it was sticking? sounds like it is now trying to stick closed and not feed enough gasoline to meet demand.

 

yeah i took it off ad cleaned it again the idle jet was clogged is there some way i could restrict the amount of gas going to the carb because now it floods out when i give it gas

 

no. there's no way to do it. that's the job of the float/needle valve.
floods out? do you mean bogging down when you give it throttle?

 

yeah but only when i give it too much gas it will rev upto a certain extent then it kills

 

Do you have a fuel filter on this machine?
