I Just bought a Bicycle Engine Kit off of eBay and put it together and was expecting it to run...Im almost always wrong. I checked to see if there was spark and that was all good then I put some gas into the cylinder and was expecting it to fire right up but It didn't. I am wondering if anyone knows much about these bikes and would know what the problem is, I was thinking it could be that the spark gap wasn't the proper distance apart but it matches what the Users Manual says. If anyone knows what could solve this that would be great.
