Honda GCV160 Engine - will not start
So my mower's idle started loping last season, fall 2013. So this year I changed the oil and the spark plug and gapped it. It still ran with the lope, but it ran. Now, after about 4 hours run time since the change, it started shutting off on me, and sometimes I could get it to start after several pulls - it would either start at a very low idle and die off, or start at a low idle and ramp up. Now, it will not start at all. I see oil in the air filter, and I'm pretty sure I smell fuel in the oil. The plug is not too dirty, but it did have some carbon on it that easily came off with a wire brush. Any ideas???
