As you know my motor won't start. It ran before I did said work. Question is, I have spark, I removed the fuel line coming from tank to fuel pump .It is getting fuel to pump. I removed line from pump to carb. Gas exits pump when I squeeze bulb between tank and fuel pump. So gas gets to pump and exits. I removed line connected to carb and gas comes from there. I put this line back on and tried to blow thru line. I blew air thru the line coming from fuel pump to carb. I could not. Seemed when connected to carb you cannot blow thru. Should I be able to, or is the needle set not to allow it to go thru. How can the fuel pump push gas to carb if I cant blow air to carb? Is this correct or do I have a problem? I just put in a new needle and seat.
