For you to have found a mouse nest on top of the engine, then that tells me that it's been left idle for a long time. Like maybe as long as over the winter.

The 30 seconds is about the time it takes for the engine to run the carburetor dry. If left along for another while then that'll allow time for more gas to reach the carburetor and then run again until it repeats it's cycle.

You may have to remove the carburetor and give it a real good cleaning. No, i don't think the heat has damaged the valves because if it had, then the engine wouldn't start at all because you'd have little or no compression.

Look at the carburetor you may have had a dual problem there and one is not related to the other.

Hope this helps and good luck.

Tip

Lawnmower fuel pop


Does your lawn mower or small engine give a big pop or bang when u shut it off after it has run and heated up for a while? I think this is from the hot exhaust egniting the gas fumes still coming through the engine. This may clean the carbon out of the muffler, but it may shorten the life of the head gasket. Either or it sure does scare bystanders, and wakes up the neighbors. To keep this from happening, just let the engine run at low idle for 30-40 seconds before shutting of the spark. Works for me.

2008 Chevy Uplander has 21,000 miles. Nno heat from rear heater at idle. Disconnected hoses and flushed, water flowed good. Reconnected hoses and still no heat. Raised idle to 2000 rpm and got good heat....


Uplanders with the 3.9 engine are prone to no heat at idle speeds. Probably weeping head gasket. Air bubble trapped. Dealers will remove rad cap and let it sit at about 25 deg. angle for a couple hours. Good for awhile.

Early 1990's 12 hp tecumseh runs until hot then backfires & dies


Coil failure! The heat is what triggers it. I bet you that if you take the cover off the engine you will find the remains of an mouse nest. The nest blocked the airflow and damaged the coil.

In the spring the shop I work at gets a lot of this kind of problem. Critters love to build nests where they feel safe from weather and predators. Your mowers engine....is just one of those places.

Good news is: You can easily replace the coil yourself. The part for this style mower is available online....even through ebay! You can do the change yourself and make her good as new!

Just as an aside. You may want to check compression on your engine if it ran hot for so long. Make sure the combustion chamber isnt packed with carbon and oil coking! If you have pull start and notice higher than normal effort is needed to start it might be a sign of this problem.
The fix there is also pretty simple. You just need to order a new head gasket. Hey....while youre waiting for a coil why not wait for a head gasket right?
