Introduction

Here�s the Mower, Ready to be fixed up, and the workspace.



The engine was covered in a thick layer of muck, while underneath there was a build up of oily much around the engine base & crank, there was also no oil in the engine itself.



Once I got the engine off, I found it trickier to handle on the work bench than the Victa�s I�m used to. So I knocked up an engine stand using a milk crate, as so.



After giving the engine a bit of a clean back, I found the air filter to be filthy, and the carburetor needed an overhaul.



Inside the engine I found the head area severely carbonated, to the point where the carbon had started to bridge across the head itself. The valves, piston head, cylinder head, ports and valve guides were all encrusted heavily.





Inside the crank case there was confirmed to be no oil, however there was still a nice residue over all parts, and everything was clean, smooth and moved freely. The cylinder was smooth, and not scored, as were the skirts of the piston.
