[Honda-C70] Re: Runs. Doesn't. Sigh. Hints? Please?

 

Thanks much. I'll check that (though I'm pretty sure I got the float right). UPDATE: I did go out again tonite and it didn't start -- took out the plug which is pretty black, cleaned it up a bit and it started up fine. I didn't check to see how long it ran, though -- so your thesis could still hold true (about burning up the fuel in the bowl).
