Got one in yesterday
Couldn't get it started so did some troubleshooting. Wasn't getting gas pumping the bulb. Checked the fuel filter. The cast metal part was bad. The 'hole' in the tube was blocked - couldn't blow through it, held up to light there was nothing shining through. Probably drill it out easy enough, but not a good sign. Took the filter off for now.
Next found the air filter was installed crooked and had pinched the fuel line closed. Loosened the screw so it wasn't pinched and the motor started right up. Fairly loud, but not terrible. Installed on a staton friction drive. Throttle cable needs a pretty small bead. Not the smoothest motor - at idle the whole bike was like a giant vibrator. Miley Cyrus would love it. Probably smooth out after break in.
Given the issues, maybe these were seconds or returns. Nothing that can't be dealt with for the price.
Guess I registered five years ago, but this is my first post. Go me.
