can anyone tell me where I could get a piston/sleeve set and crankshaft? And if you could tell me the part # and if it's interchangeable with other pixie engine parts or novarossi parts. This is the Pixie 163r12 3 port engine by trinity. I'm getting poor service from trinity and this is why I'm coming here for answers

I have a new piston sleeve, but no crank. pm if interested
