Got this the other day...."Was working, now doesn't start".....
Check obvious...bore and rings look ok.....pop starter off.....
Bazinga!
See if you spot the old rings versus the new ones?

First question I would ask is what is all that crap inside the motor, can't say I have ever seen that sort of rubbish inside one of these motors, even the ones I have picked up where people have pinched the starter and left it open. Rings are pretty obvious but it shows how far these motors will run before they won't start any more
MF pretty simple, easier to make and in out climate down south they don't seem to have overheating problems and you shouldn't be out mowing on a stinking hot day anyway, not good for you or the mower.And DB, "it was working and now it doesn't" I can assure you it was "working before" they always left the shop new in working condition
MF, never noticed any difference between them and I have fixed so many I have lost count, I used to keep a record but I ended up loosing count. My problem now with these float needles and having to buy 100 which is going to cost over $800 I will have to work really hard at my cost neutral hobby just to break even and as I have probably 20 powertorques sitting here to refurbish at the moment, that means I have to scout around and find another 80. I'm going to end up old by the time I fix that many
Chip away and enjoy the adventure in hunting them down. One good thing about the PT with less fins is they are newer. I have one I found without a starter and primer cap needle and seat, and after adding the missing bits, it runs like new. I bet you are in the situation wher you have more engine husks than starters to go with them. I got a good score recently where I happened to see a guy loading a derelict Victa with PT tho go to the tip and I said hold your horses what bits can I get off that? Well it turned out the starter was good. Thank you!! Also managed to get a pair of good rear 7" wheels. Perfect for the front of one of my "pets". I wanted to grab the primer cap etc from the carby, but alas the guy originally throwing the whole machine decided he wanted the whole throttle, snorkel and carby set! Guess I couldn't begrudge him that.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
Hi MF, you are right, I have a lot of PT motors here without starters that were ratted by persons unknown and then I have a pile of motors that won't start, they get pushed aside for a later date to re-ring and replace the lower seal, then they will be fine. If I ever get a chance I then need to clean out the motors that have arrived without starters, put a starter on them and check the compression as a first test. I know most of these motors that are missing starters are most likely good, but the starters have been ratted and sold on ebay for more than the seller could sell the complete mower. And to go over this once again 80% of these mowers are dumped because of a faulty float needle, the other 20% is because the body has rusted in the corner
It's a real dilemma having more motors than bodies our there. You can stick them on old Victa four stroke decks with junked motors. The starter issue is trickier. I would only fit them to motors that pass the compression test to save you the work of repairing them with seals and rings.

I have a standard procedure I go through with all these Powertorques. First step is remove the decomp valve to ensure it works. Second step is remove the spark plug to check for spark, making sure the throttle is in the open position. Third step is fit an old spark plug in the decomp hole and pull the start cord to see what compression feels like. This controls my next step. If compression is low I just pull the motor off the base and put it in the pile of motors for later. If it has compression I fit my test carby and see if it will start. If it won't start, but will with a squirt of starter fluid in the plug hole then I put the motor in the engine pile with a note on it that it needs the bottom seal replaced. I would say the failure rate on the ones I get that won't start is probably about one in six so for ever 10 Powertorques I pick up I probably get 8 running as they should. I then strip them to the bare chassis, repair anything on the chassis that needs repair/welding, sand the chassis back, paint it and then reassemble using good/new bits and somebody will get a good mower. Is it worth all the effort, probably not, but at least I get pleasure out of salvaging these wonderful mowers
It's a shame you don't turn some sort of profit. The public at large assume four strokes are where it's at. It's nice to give a second life to these discarded/ abandoned beasts with plenty more to give, but how many of the new owners will wreck them through abuse or straight petrol, or just give up because of a minor problem that is readily overcome? It's good you gain satisfaction out of it. Many people don't get that out of their jobs.
