I've finally got my lawnmower that I got for free working. The self-propel system was jamming so I looked into the gearbox and the gears were stripped to pieces. I popped the covers off of each front wheel, took off the wheels, and then took the gear out of each one. I also cut the belt off because the gearbox was still jamming up. It's not harder to push than a normal, non-propelled lawnmower.


The problem is oil. About every 20 minutes you have to check the oil to make sure it isnt empty. I've spotted a leak on the back of the engine (bottom of the crankcase). It seeps out from between the two halves of the engine. Is there a gasket that goes there that could be bad?

Another problem is the recoil starter. On the first cold start it pulls fine (even though it's missing the plastic handle on the end). But after you shut it off and it's still warm, when you go to pull the string it wants to stick and yanks the string out of your hand. Any ideas? It will need a new string with a handle anyway soon.

As I recall this is a Briggs and Stratton engine...

The crankcase is in two halves that are seperated by a gasket. It is not too difficult to replace the gasket but it does involve pulling the engine, pulling the hub and pulling the lower half of the crankcase. You will also want to replace the crankshaft seal at the same time.

The recoil starter relies on a clutch that has several steel balls inside. Either there is crud in yours, or someone in the past has greased it (they are designed to run dry).
