Question about Craftsman Garden
I have a Brigs&Straton 6.5 Quantum lawnmower will not stay running. I can keep it running by restricting the amount of air entering the carb with my finger (choking it) The mower will start if it is primed but as soon as the extra fuel is burnt it dies. It will stay running if I spray fuel into the carb, if I stop spraying it dies. So when I stick my finger in the carb I am making the fuel mixture richer by increasing the venture effect(I believe). The float level is adjusted to level with the cab upside down. Any suggestions??? Randy
The problem is in your carb.,at the bottem of the carb. there is a bolt that threads in to the carb.pinch off the fuel line so that no fuel comes out after the fuel bowl is off the mower.now look into the bolt that you took off.there should be a hole oppisit the head of the bolt.there are also two holes that go through the sides.these holes are the fuel intake to the carb,the hole in the center is the fuel nozzle.most likely you have dirt blocking this hole and not letting the motor get enough fuel to run.thake some carb cleaner and spray it in the hole.take an air hose then blow the nozzle out.while you have the screw out take the bowl off and check to see if there is any water or dirt in the bowl.after cleaning.reinstall the bowl and start mower again.should be running ok now.if not let me know and i'll guide you through another fix.let me know if this helped or not................
