Got this “100cc” engine kit on Amazon. Completed build and couldn’t get it to start. Carb that came with the kit was damaged when I got it so I installed the one shown above with auto choke. That did not fix the problem. Looking for any advice on what to try. I am new to motors and new to this forum. Here’s what I’ve done so far: Ensure fuel ratio 16:1, check for good spark, check throttle working, messed with idle adjuster, gapped magneto loop, checked direction of magnet, tried riding at various speeds and combinations of choke / throttle. When I try to start it I don’t even hear a single pop. Don’t have the air filter on. Any ideas what I could be missing?
