Victa Mower wont run.
 

Hi All,

Is any one able to offer constructive advice?
We have a Victa Corvette 400 mower.
The problem is that it loses revs and just before it cuts out it picks
up the revs again. It is continous in about a 5 second cycle.
We have cleaned the carb and changed the spark plug, renewed the fuel
and changed the air filter. Is there any thing else I can do before
submiting defeat and paying to have it repaired?
