OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Tecumseh / Kirby Engines Sparks from the muffer of Victa TVS90 engine

Hello,

Lately, my Victa mower with TVS90 engine (Tecumseh manufactured) is not going very smooth. So I changed the engine oil (SAE-30 as recommended) and things are all right again.

Yesterday when I was mowing, the mower blade wasn't spinning very well, kind of choking indeed. I disregard it and keep going, all of a sudden, sparks come out of the muffer and I turned it off straight away.

Then the engine never works again (almost never, I successfully turned it on today for a while, then I turned it off because I removed the air filter for cleaning).

I wonder if this damages the engine by any means and if there is any DIY way to get it on the lawn again.

Appreciation to anybody who can help.

AJ,
It sounds like you have carbon deposits comimg off the cylinder head and blowing past the exhaust valve into the muffler.
