I have a 1995 sportsman 400 that wont stay running while at idle. It almost feels that it is running out fuel. I changed the fuel filter and took the carburator apart and cleaned it. I dont know what else to do. Any help or comments will be great.

 

floats could be sticking or trash in the tank or the valve has got trash in it

 

check your throttle cable play, if it's too loose then your etc kicks in and it won't idle, but itll run good everywhere else

 

if by pulling the choke out helps it to keep running then its a lack of fuel problem for sure.

 

check the vent line for pinch or stopped up

 

Could be a vacuum leak as well. Spray carb cleaner around the carb boot, cylinder gasket etc. If the idle speed changes. Vacuum leak.

 

could be just old gas mine wont run if the gas is in the tank for a week maybe two. it spits,sputters and dies

 

Check Kerbmonsters solution, the ETC, electronic throttle control, is probably out of adjuctment and is easy and costs nothing to fix.
