OutdoorKing Repair Forum Forums Finding and Swapping Tip & Curb Side Finds Victa Queenslander

When you can't finish a project properly, just put it in the shed and start another,,,,,
Right colour.......
I was given this power torque. I was diagnosed as broken rings and badly scored bore.
I pulled it apart. an 98 model.

Looks bad, but I got the rings off and cleaned up the ring crooves and piston. Rings were pretty good and bore was good also.
Cleaned the carb and put it all back together...
Works pretty well.


I'm keeping this one....
And I have 3 lawns to mow today which should pay for parts for my orange power torque...

Well done speedy, so what did you actually do? Did you just clean the piston up, reused the original rings? What did you clean in the carb and do you have any rev control on it?. Did you see inside the crankcase as to what controls the revs in there?. I am going to pull one down when I get a bit of time to see if I can work out what exactly goes on in there. I think they have potential as a good strong motor if the revs can be controlled. I believe the carby is blamed for a lot of these being thrown out and I don't think they are the real cause of the problem, just part of it. They must have sold millions of poppets, diaphragms and "O" rings to no avail, mower then dumped

speedy amazing you got it running again in dat condition
do you know history was it run without oil in fuel, I worked on a lot like thatover years in shop we would rebore new piston ring ect
norm may be you need to do preasure test crank case to test seals,they do this on most 2 stroke motor bike engines before and after rebuild , leak down test to check for air leak at seals
seal leak make motor running lean

Good call freebird, where is the best place to take a leak down test on the crank because I will have to make up a fitting of some sort.

sorry speedy this not about you posting will make it short

norm make adapter for air fitting to sparkplug use tyre preasure guage, block exhust and intake port .
put piston bottom dead centre add low air preassure watch guage check leaks spray soapy water
look utube how to leak down test 2 stroke better explain it to you than me

Thanks freebird, I have made up a leak down tester for my Honda motorcycle but that is a smaller plug and getting the core out of a spark plug isn't easy

Hi Normk,'
I took the rings off the piston, and clened the ring groove out with a broken ring, had to file some parts as the ring was jamming. Rings were good so reused them, bore was good and the compression is gained by bore and rings not piston. Piston looks bad , just used wet and dry sandpaper to rub a few bad scores off. Ran the to and bottom of rings over sandpaper to get carbon off. Just cleaned carb. I even used old big oring, just smear oil on it to make it slide in.
The throttle didn't give me much rev control, but with these engines, when they come under load, they seem to develop more power.
I mowed two heavy lawns yesterday with it and it handled it. I put a knife edge on the blades with an angle grinder just for a better cut.
One more heavy lawn to do today....... I love these power torque engines, now I have two. I still have to nut out the module problem with the orange one.
My mate was watching me and said he wished motor bike engines were that easy to work on.

freebird I don't know how it got this way, not enough oil I guess.But the rings were stuck in the piston grooves , that's why there wasn't much compression..
cheers

Thanks Speedy, the power torque would have been a great mower if it had been fitted with a decent carby, not sure how many of them I have but hopefully one day I'll get them fired up

Nearly every 'chinese' power torque engine (ie after about 1994/95) i come across new or old is scored to some degree have had to through at least half a dozen away (beyond even a hone), and yet nearly ever 'aussie' power torque i come across is in great to perfect condition, go figure! Sure proper maintenance has a bit to do with it, but the older aussie made engines are a much more durable engine. If i ever need a replacement i buy an older aussie made power torque, swap over the later cowlings and ignition coil and she's good to go.

This is a 98 model. so maybe it's chinese.
I mowed a heavy Bundy today, the 3rd one i had to do. It went perfectly.
It was for chinese people.................
fruit and vege pickers at Bundaberg. 4 or 5 live in a nice dwelling, earning good money on a special visa... the farmers up need them as the locals can't handle a bit of hard work. I like them.

just want to get my orange pt going.
speedy

Is there any way to tell which of the Power Torques are made in Aus and which ones are Chinese

See this thread mate, it mostly has to do with the design of the cooling fins on the engine block.

Gotcha Dan, good info from Rob there, I'll have a look through all mine and see what I have in there

Diggin up an old thread, picked up a Queenslander yesterday from an old lady $15, was missing the airfilter cover and the fuel tap had been left on and flooded the carb with oil. I also replaced the sparkplug and fuel lines, she started first pull and is one of the smoothest engines ive come across. This is the earlier aussie made engine but stamped 1996, the latest ive ever seen. It already had brand new genuine blades and primer cap, and came with the Victa spark plug tool. I have such a soft spot for these mowers/engines sometimes hard to part ways.

Nice one Dan, Are you going to keep it.
speedy

Oh right I get it, the maroon colouring. Makes sense. Haha.

Looks in pretty darn good nick too. $15 is a steal.
