Victa mower hiss/power loss

[Hill-Billy]

Not sure if this is the right forum(i am at least a tree-surgeon taking time out to attempt to cut our lawn!)? Any mower experts out there can shed some light on my Victa mower hiss/power loss I'd appreciate it - great mowers but don't want to buy another just yet.

Sounds like a problem with the decompressor valve.

 

To test this theory replace the decompressor with a spark plug (same thread) and blank off the vacuum pipe that operates the decompessor.

 

It will be more difficult to pull over but may cure the problem.

Thanks, I'll give it a go and see what happens!
