Hi, I have a moped that stopped working in the past 24 hours (I didn't change anything in that time period) . It had a huge air bubble in the fuel valve and was not getting any fuel. It had enough fuel in the tank but I went ahead and added more. I had an inline fuel filter on it but I took it off (it was only 30 micron, I'm getting an 80 micron soon) because I didn't know if it was restricting fuel flow. Now it just has the fuel valve on it and I got rid of the air bubble and it still wont run. When I try to start it, it seems like it will start but it never does, I took off some covering and watched to see if it was pumping fuel and it didn't seem like it was. I heard from a guy that sometimes hot weather (its been really hot where I live lately) causes a lot of air bubbles which makes it hard for the moped to start but I wanted to see if anyone felt differently and if there is anything I could do to fix it (the moped has new spark plugs too). I would really appreciate any advice.
