Hi folks,

This victa has maybe 25 hours on it. It loses power at full throttle, then almost stops whilst cutting, then reponds to choke. It has a yellow spring on the diaphram. The diaphram cap seems to be restricted.

It has a yellow poppet valve with A and C marked, and the number 4. This poppet valve is not continuous?

I put a long grommet into the carb for the cut off switch for a possible repair, maybe did not shorten it enough. The original seemed damaged.

Seems to be some damage on the intake manifold O ring, but after removing it, same goes for the starter housing.

Bore, piston ports, decompressor, seem excellent

Plug looks good

Bore not marked, piston moves freely.

Fuel supply, fuel pin, float all seem ok.


The mower would run at full throttle and work, and stop working, then go back to normal again now and then.

Hey guys

Any Ideas for a dramatic loss of power whilst cutting?

Taa

See ya
