Hi Tyler, Haven't checked on the Chinese block ratio, but at a guess probably 15% I will check tomorrow. I don't find any difference with the Chinese ones, obviously Victa had strict controls on their manufacture. The problem now is I am getting into the "I think I have been through this pile before" so the failure rate will go straight up. The ones I had been going through were all from a pile of motors I picked up from a bloke who was mostly looking for good Victa bases so he could put 4 strokes on them, he didn't know how to get the Victas to sing again, this is why the success rate was high. There is still probably 15 or so that I have previously labeled as not starting so no point in me testing those again. Still leaves a pile that need to be gone through, but it all takes time, everyone has usually had something ratted of it or is broken
