2-cycle engine troubleshooting
The 2-cycle engine of my Mantis rototiller won't start.
Sometimes, it fires and then runs roughly for a few seconds, but then when I push in the choke, it stops. I've tried pushing it in just a little, or very slowly, but it always quits when I push the choke. I've blown through the tubes and nothing is stopped up. The gas filter seems fine. There are no kinks in the fuel line. The gas cap looks okay.
I've replaced the spark plug, air filter, and gas (confirmed that the mixture was correct). I've tried adjusting the two carberator screws per the manual.
I'm leaning towards taking apart the carberator, though this machine has received very little use so I'd be surprised if that was the issue.
My best guess is that I'm not adjusting the fuel mixture properly.
Any trouble-shooting advice would be greatly appreciated.
