2000 6.5 HP Tecumseh lawn mower will not start

I purchased a Scotts self propelled mower from an individual who had it sitting outside. It did not start. I replaced the spark plug, fuel line, sanded the magneto, emptied the old fuel and replaced with new fuel. I cleaned out the carb as well as replaced the gasket the needle and the seating. The engine will start but then stops. I am puzzled at this point. Does anyone have any suggestions??? dzton |

Would the breather element effect the starting and stopping issue?

Breather element or air filter? Breather element. I already replaced the air filter.
How nasty was the carb before you cleaned it? Nasty!
Did you clean the bowl nut? All 3 holes? Yes.
If you look into thoat of the carb...and prime...do you see fuel coming from the tip of the main nozzle? No, I removed the carb, broke down the carb removing the main nozzle. I did need to add two new "O" rings. (Use a flashlite too look in.)
Did you hook the wire clip of the needle over the float the float tang? Yes. Did you set the float level? No. Not sure how I would set the float level. It appears the needle goes into its inlet once placed on the float.
If you loosen the bowl nut...does fuel flow out? Yes
When you installed the needle and seat...did you have the carb off of the engine? Yes.

Dont worry about the breather....they "never" good bad. When you replaced the 2 o-rings on the main nozzle, are you sure you removed the old one. (The top one usually stays put and has too be dug out.) Are the governor-carb linkages as they were before you removed the carb? Again...make sure it is priming when you press the primer bulb. (You should see it coming out of the end of the main nozzle, into the throat of the carb.)  Be sure that # 241 is in place....screw #238 must be in its holes, or the carb will never prime. (The screw blocks off a common passage that it shares with the primer system.) Without the screw in place....the primer charge just blows out of the hole and doesnt reach the float bowl. |

I pretty sure, not 100% positive.

Do I perfom this with the carb off the engine? Be sure that # 241 is in place....screw #238 must be in its holes, or the carb will never prime.

The two screws are in the holes.

The bottom one may have rotted away....the top one is possibly still stuck in the main tube.

Do it on the engine...just remove the air cleaner and cover too take a look. Make sure you have at least 3/4 of a tank of gas.

Excellent.
Check that both surfaces that the large O-ring (part # 631028) seals are clean. (The float bowl and base of the carb.)
