My understanding is that Aztech Marketing, the importer of Enya engines no longer sells engine parts through dealers and has to be purchased directly from them at full retail price plus $7.95 for shipping. Does anybody has any update. I had to pay them $17.50 for an exhaust header set screw, which probably should have cost 50 cents. I like these engines but if they are trying to zing me on parts I think I will start looking at other manufacturers
