TORO 6.5 RUNS FOR 4 SECONDS AFTER PRIMING THEN DIES.pUT IN NEW SPARK PLUG,new gas,but after priming run for several seconds.. it dies again....can you help...sounds like dirt in carb??/ It had run perfectly for past 3 weeks,but problems now..

If it has a fuel filter on it change it and that should get you going again. If not the dirt that was in the tank is prob in the carb cleaning the fuel bowl and jets should get you up to par. Hope that helps

I don;t know what engine is on your mower but if it has the self contained electronic ignition coil I have seen happen on several engines. It would run good for several min. then the spark just stops . And it will not spark again until it sets and cools . Just make sure it is the ignition that is not working.

I had a similar problem. I'll bet I took off the carb. 5 - 6 times and cleaned it with no success. Very fustrating! One time while checking the fuel level I accidently left off the gas cap, I started it and while running I put the gas cap back on and started to mow and about 10 seconds it died. I thought could'nt be! So I loosened the cap, restarted and it kept running. Any way the small vent hole was plugged. Thats my story!. Good luck.

Have a Toro GPS5 600 lawnmower. Starts with Choke on, but dies if you move off choke. Also, runs fast and slow when blade engaged. I heard carb for this unit are no longer available. Help

Bad fuel or check for water in your fuel! Clean your carb and float bowl. Empty gas into a clear container, if there is two levels of liquid one of them is water. Of course make sure you have good spark plug.

Try taking off the fuel bowl and check for debris or ice in it.If there is hardly any fuel in it you may have a plugged or pinched fuel line,try blowing back through it[might get a littl gas in your mouth],turn off the fuel and remove the line at the carb and the tank.If niether of these pick up a new spark plug and try that.

Remove your fuel filter (in the tank usually) and, replace it

Hello:

There are 2 Possible Causes for this Problem.
1- The Carburetor Requires Soaking and Cleaning.
2- The Valve Clearances Require Setting.

Was gasoline left in the tank during off season? Sometimes gas will break down and clog the jets in the carb. The priming bypasses the carb so when you put fuel in by pumping the bulb it runs, but dies becasue no additional fuel is coming through the carb after the primed fuel is burned off. Sounds like you need to clean the jets in the carb and in the future, use Stabil in gasoline to keep it from breaking down.

Hi

When the engine stops check the spark at the spark plug.Check compression(remove the spark plug and ground the plug wire on the engine,seal the plug hole with your thumb.Operate the starter.If the compression preasure blows your thumb off the hole,the compression is adequate for the engine to run.Now priming the engine(put some gas into the spark plug hole,back the spark plug and try to start the engine.Let me know. savumihai71 regards
