Just would like to get some advice on buying an engine. I had an evolution .45 trainer motor and after two and a half gallons it is toast. There is barley any compression left and the rod bushing is so worn it clanks in the stroke. I was thinking about another evo motor. the .46 or the .52 but I'm thinking of maybe another brand. I need an engine to last more than one season. Is it common for an evolution motor to wear that quick? and what 2 stroke sugegstions do you guys have for a 6.5lb p-51
