Thanks for the info guys, ok so on the diaphram does it have to be seated, or does it just lay flat on the reagulator body? I took it all apart and cleaned everything and put it all back together, I dont have all new parts to replace them with so I have to reuse what I have. I tried to start it but its not fireing now, it wont start. But its not leaking fuel no more. Ive got a OS #7 plug it it and useing Byrons 20\20 fuel (the purple stuff)
