My lawnmower wont start. It has no compression and makes a ticking noise about every time the blade turns?
Jill S asked:
I can pull the starter will no problem and the blade just spins making this noise. There is no resistance when I pull the cord. I mowed the front yard, thought I was hearing a weird noise from the mower. Then went to mow the back and it quit after a couple of minutes. Now this is where its at. Any advice?

Ticking noise is not good. You may check your spark plug, remove it, put your finger over the hole and pull. If still no compression then you may have internal damage.
Last effort is to drain oil and look for metal flakes or pieces. If you do find some you may have blown your motor. GG

No compression is one of two things. Either the valves or piston rings. Either of the two involves going into the engine. Chances are that it will be best long term to buy a new one. As cheap as they are now-days they are almost disposable yearly. A push mower from Wal-mart are as low as 100 bucks. At a repair shop you are looking at at least $40 / hour plus parts. russbillen

The ticking sound you hear is the connecting rod, if you run a small motor low on oil it is very common the rod will snap, it will have no compression, the blade will spin because it is hooked directly to the crank, but the piston will not move because the rod is broken,
the sound you hear is the rod slapping against the walls in the motor, if it is a small push mower it is cheaper to go buy anthter one than fix the motor, go to walmart or home depot a new push mower is about 120 bucks. Jason C

If it really has no compression you have a choice of either getting an overhaul or buying a new mower. If the mower is an inexpensive one, replace it.
An easy way to get an idea of whether it has compression or not is to remove the spark plug and hold the end of your thumb over the hole while pulling the starter. If you feel no, or little pressure on your thumb, it’s decision time. The Outcast
