Hi all,

I was moving, hit something hard which caused mower to stop dead. Tried to start again, nothing. A few more pulls and I'd get a 'pop' sound like a backfire. Thinking somehow it was flooded, I removed the spark plug & pulled the cord a few times, no fuel spit, spins freely, no problem. I put the spark plug back in, similar deal. Kept pulling, occasionally it would try for a few seconds, then nothing. A few more pops. I inspected the underside, the cutter blade and shaft seem ok. I gave up and went inside.
One thing I did notice, sometimes when I pull, it felt hard at a certain point (but not always), almost like it was too much compression? But it only did that a couple of times.

I've had the mower stop suddenly many times when mower grass that was too thick, but always started back up again.

It's a chonda engine on a rockwell (yes, not a great mower, but, it's always started 1-2 pulls and has always been fine. I can't afford a mower, so will have to get this one fixed.)

Ideas ?
