OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Seized Powertorques

Seems like it is the season for seized PT motors, My son has brought over a few recently and I think there was 4 that were seized and a couple had had the starters removed and water had got in. One he picked up from the nature strip outside a mower repair mans place,was one that the starter had been removed because you can get $25 for a pull start but struggle to get $25 for the complete mower. My son was talking to the chap and he gave my son a brand new Victa base, no wheels,not sure what it is but it is for the post PT bases. It still had the Bunnings receipt on the handle for $400 on it, bloke said he needed the motor from it, I can't get my head around it, if it was a new motor he wanted you can get a Chonda type motor brand new for $160. I will have to go and talk to this bloke to understand what he is up to.

I have two that I just can't bring myself to chuck out. I want to use them as practise, but I haven't been able to undo that damned crank pin.
I have attempted to make a socket to fit, but it keeps slipping off. My next strategy is to use a rattle gun with this socket and apply downward pressure at the same time. I just need a 1/2" to 3/8" reducer.

MF they do undo easily with a rattle gun, the 1/2" to 3/8" adapter worries me a bit. The other thing is there is a couple of different crank pin nuts as well so you need a couple of modified sockets

The reducer should handle the torque requirements of this job.

And yep, the two Powertorque engines mentioned have the two different types of crank pin nut.

I'm going to have to go back through my growing pile of PT motors that will not start for some reason. These motors have compression,spark and have all been fitted with a known good carby and a squirt of starter fluid in the plug hole. The starter fluid in the plug hole should remove the chance of a lower oil seal leak and the motor should give at least a hint of firing, but these motors make no attempt of at least one fire. When this happens after a number of attempts I just remove the motor and put it in the won't start pile. Any thoughts

Sims Metal ?

BB wash your mouth with soap and water, how dare you suggest these Victas are ready for the scrap, still have another 50 years left in them

Tongue in cheek comment

I'd like to see how you take it if someone said to send a non starting vertical four stroke off a Scottie to the metal munchers.

Sorry BB I couldn't work out how to put in a smiley.
MF totally different ball game, so many small components in a 4 stroke that as they get old can fail. The Powertorque motor only needs an oil seal couple of bearings and a set of rings and it is good to go again for years

Hi MF,

If you're referring to a problematic Kirby Lauson or an early flogged out Briggs, well frankly my dear I don't give a damn or in other words I couldn't give a rats toss bag (to quoin a phase from Malcolm Blight) as there's plenty of better choices out there now to power a Scotty.

Cheers,
BB..

Yeah i have 3 sitting here,, all no spark. New briggs 3.5hp for $270 is hard to beat

Yep that's it, Chonda's are even cheaper. I replaced my ailing Kirby on my 20 inch with a late model Briggs. I will say that I prefer the look of the HK30 with the large forward facing fuel tank but the numbers just don't add up at times. So it is what it is I guess.

Cheers,
BB.

You got it. I guess I'm comparing bananas to pears.
It would be nice to see a red Victa 125cc power unit adapted onto an SB reel mower.

G'day all,with the Powertorques as long as your comp is good and crank case seals are good and carb works,all the ones I have had that did not run I replaced the ignition module or the coil even if you test it for spark and the plug shows spark I replace the module first then if it still doesn't run replace the coil ,use a coil and module from a motor that you know runs.
Just commenting on what has worked for me with a non runner.

Good call on that Max, certainly worth a try, it isn't a compression problem because these motors have reasonably good compression and should give the slightest hint of wanting to run with a bit of starter fluid in the plug hole but there is nothing so it must be a spark problem
