Hi, I have Victa PowerTorque-160 that has nasty habit of fouling plugs on a weekly basis. I have tried different plug brands, precise fuel mixing, new decompression valve, head gasket, checked the exhaust but yet no luck. This mower starts first pop (with fresh plug of course), runs great with heaps of grunt and is probably my favourite mower out of six sitting in my shed, just a shame about the plug issue though. Are PowerTorques hard on plugs in general? Cheers cool
