I have a Toro push lawnmower with a "Ready Start" engine (similar to this one); I just pull the cord and it starts.
I was halfway through mowing the lawn when suddenly a ton of white smoke came billowing out of it. I read that this could be due to the air filter being clogged, so I cleaned it out as best I could. Now, the mower won't start at all, no matter how many times I try.
It has oil, it has gas, the air filter is now cleaned (or at least, cleaner than it was)...what could the issue be? I've had the mower for three years and this is the first time I've ever had it not start.
UPDATE: I tried it again later and got it to start. But here's what it does: it'll run for about 5 to 10 minutes with no problem, and then a ton of white smoke will start coming out of it again. If I turn it off, wait a minute, and start it back up, the smoke will clear up. Then it'll run for another 5 to 10 minutes before doing the same thing again.
From the comments here, it sounds like oil is getting in, but why would it happen on and off like that?
Regardless, I think I'll take it in for servicing since it probably needed it at this point anyway.
