Check fuel pressure at pump? if you have pressure, check float NEEDLE WIRE that helps open the valve.
if it runs ok above 30, suspect bad carb main valve or dirty float bowl.
You float is stuck in the up position. Inside the bowl in the carb.
do you mean it doesn't run unless you romp on it or that when it runs it maxes out the rpms? if it always runs at max rpm then your throttle is stuck, remove the air filter housing and spray the cable and connective parts (back of carb) with carb cleaner... if you mean it doesn't run unless you take it to max rpm then you probably need to get a carb kit for it (be sure to see if its a spark plug or timing issue first)
The float is stuck in the OPEN position. Try sharply rapping on the float bowl several times with a non -metallic object. Screwdriver handles work great for this. I seriously doubt that the float went out of adjustment all by itself. Worst case scenario - take the float bowl off and spray carb cleaner around inside.
Inlet needle in carb sticking open; it runs in through the carb.
Most likely the cable running from the peddle to the carb is seized or possibly the carb is just stuck open. Easy way to find out is to remove the intake hose from the carb and see if the gate is open or closed. Open is full throttle. Troubleshoot from there.
Yes it does but all the computer does is regulate the spark to the egine and runs your throtle body and the batery and alternater give it power?
Your float is sticking
check the ammount of gass an air entering you carb that could be why it runs that way all you have to do is adjust the screws on the front of your carb it would be smart to put some carb cleaner in it too
When there is no carbohydrate intake the body runs on fats
you did not say if was carb but if so spray pump in the carb is a good place to start
Possibly the float is stuck or the needle valve is stuck or has dirt in it. Clamp off the fuel line going to the carb so no new fuel can get in. Start the vehicle & run it till it runs out of fuel. By doing this if you're lucky whatever is stuck in the valve may sink to the bottom of the bowl. Unclamp the fuel line after the engine runs out of fuel and restart the engine. Hopefully it will now be o/k and save you having to disassemble the carb. If it still does it, it's time to disassemble and while you're at it you might as well put in a kit.
