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
