OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Power torque wont rev above idle.

I have been through an ordeal with a power torque engine.
I have a block here that has been bored oversize by 0.40.
All looked good so I built the engine.

It would start easily.
However it would only idle & not rev above that.
It was back firing through the decompressor at times.
Then it would stop running.

I read all the related threads.
Checked all o-rings rebuilt & replaced carby.
Tried all I could think of.

I ended up stripping it back down and putting all the parts on another block with a standard size bore.

I had the same fault, engine would only idle.
Checked and rechecked everything, I was even replacing good o-rings.

I feel stupid but it ended up being a blocked muffler.
Thought I would share this.
