Recently I bought a half finished seduction freestyle with a ys 63fz. When I bought it the engine was running great (I've runned it with wildcat 30%) but 4 weeks later I wanted to make my maiden flight with the freestyle. Unfortunately without success. The engine didn't run because it didn't get any fuel from the regulator. At home I carefully disassembled the regulator and cleaned it but without any success.
Does anyone knows what could be wrong? I live in the Netherlands and a YS engine is pretty unique here so there aren't much people here who have the knowledge to repair a YS. So i hope maybe someone here at this forum could help me.
