i have a craftsman push lawnmower. i was tightening the wheels and put it on a steep angle?
nancy asked:
a small amount of oil leaked from the muffler. i mowed for a couple of hours with some black smoke and sputtering of the engine. when i brought it out the next weak it would not keep running. i changed the spark plug and after about 1 hr same problem. i took out the spark plug and it was as black as the old one.
you do not mix oil with the gas. runs on straight gas.

If the mower has a 2-cycle engine you are not mixing the gas and oil correctly.

change the spark plug again or try to clean it it has to burn the oil off the piston it should clear up hopefully good luck.

When you had the mower on a steep angle, oil most likely leaked into your cylinder, it is best after having your mower on any sort of a un-natural angle, to let it sit for about 30min while all the fluids return to there correct places. i would replace the spark plug one more time and after running the mower, the plug turns black again. it means you are pushing oil. a cheap and effective way to fix this problem is to run a little bit hotter spark plug and check the oil regularly! example: Champion RCJ7Y to a Champion RCJ8Y

If a small amount of oil leaked from the muffler, you got a large amount of oil inside the cylinder. Running it like you did most likely fouled the rings and now you can’t get any compression. Tryingt a hotter plug might work, but I suspect the mower is out to lunch.
