This will make sure you are less likely to round off the bolt if it’s really tight. To remove a lawnmower blade you will first need to clean the blade bolt off with a wire brush. I usually just lean it against the fence or wall to do this. Tip the lawnmower with the exhaust side facing the ground and the carburettor pointing up in the air. With all the fluids removed and the spark plug safely out of harm’s way, we can now tip the lawnmower up to remove the cutting blade. The correct spark plug is NGK Spark Plug Single Piece Pack for Stock Number 1147 or Copper Core Part No. You can re-fit a new spark plug at the very end of the service. Remove The Spark PlugĪt this point, before working on the underside of the lawnmower cutting deck, you should remove the spark plug completely and leave it removed until all other servicing is complete. With all fluids now removed we can do this without causing further problems. The next part of the servicing requires tipping the lawnmower up to access the blade underneath. There are smaller alternatives that will do a great job including Silverline 104616 Oil and Fluid Extractor Pump, 4 L I use a Pela 6000 Oil Pump – Oil Extractor/Oil Extraction Kit. Just use an oil extractor to remove the fuel and please dispose of it in an environmentally friendly way. You do not need to run the lawnmower out of petrol/gas as this can pull any dirt from the bottom of the petrol/gas tank into the carburettor and cause further problems. If your lawnmower engine runs, then I suggest running it for a few minutes to warm up the oil before extracting. Not only will you have a massive white smoke problem when the lawnmower restarts, but it may also stop you being able to pull over the lawnmower engine at all.
Tecumseh lawnmowers, like many others, really don’t appreciate being tipped up as it sends fuel and oil into areas of the engine it shouldn’t be. Using an oil extractor eliminates the need to tip the lawnmower up or over to remove the fluids. With this in mind, I strongly recommend using an oil extractor to remove all the fuel and oil from the engine. With a Tecumseh engine, you need to re-fit a lot more parts to be able to test the lawnmower and it’s very time-consuming. With most of the lawnmower engines I service or repair, it only takes a few minutes to refit the carburettor and test the lawnmower once servicing is complete. Please do not skip this section because it will save you from making a massive error when re-building the lawnmower after servicing the carburettor.
