engine cuts out/stops

[kbstorm]

i just finished puting back together an old go kart. i put a new engine (6 hp powerhorse/northern tool) and clutch on. the motor started right up and everything runs fine. the problem is that when you ride the go kart the motor kills. plenty of gas. plenty of oil. it starts right up again. if i let it just idle or run it on a lift there's no problem.
i disconected the on/off switch and it still cuts out.
is it the low oil sensor? it may happen when this thing is bouncing around. it also seems to happen on certain slopes up and down and at faster speeds.
any thoughts?
thanks.

From what your telling us its most likely the low oil shutdown. I know with my kart I never had a probelem with it on level ground but when I got into a good drift on dirt it would cut out.

thanks
other than a different engine any way to get around it?

Yes, Just unplug the sensor.

do you have old gas in your motor like one year old?

He said in his first post it runs fine on the stands so its the low oil sensor.

I has the same issue with the blue HF clone. I disabled the oil sensor and now its fine.

Just because the engine runs great on a stand doesnt mean its going to run good under load. My kart ran perfect with the stock 95 mikuni main jet but under load it would just shutdown. Its just your low oil shutdown.

Ok i get it, dont ASSume anything, i was just saying it really sounds like the low oil sensor, and i was just letting Ferrari_Motors know that it wasnt the old gas.

Ohh ok, No worrys.

thanks everyone.
where is the sensor?
hard to get information from shops. i guess they're concerned about liability. i just want the kids to be able to ride without having to restart the engine every minute.

Sounds like a carb to me. And I work on lawn equipment everyday for a living. Some little piece of something is in a fuel passage. Get out a stripped bread tie and start poking the small holes, blow it out and put it back on and try it then....

Sounds nothing like the carb, if it happens when he is going fast (oil sloshing) at certain slopes (oil away from sensor) and on bumpy terrain (sloshing again) then it sounds like the low oil sensor.

The sensor should be located on the side of the crankcase somewhere, just follow any wires you see, and eventually you'll fine it.
