Thanks for the reply. I'm sharpening the blade I took off and have ordered a new one.

I have a Snapper self-propelled walk behind mower with the B&S 7.0 hp OHV engine. After resolving some fuel system problems, I discovered when cutting that I need a new blade. The blade is like the one pictured below with the splits on the ends. Do I have to replace it with one just like it...

The carb has a primer bulb. Yes, I discovered when I took it off again that there is no accessable adjustment. There are seals over what I presume to be the adjustment screws. I removed the spark plug and it was carbonized and a bit oily but not burnt up.

It is an OHV engine model number 128607 type 0113E1 code 040726PA. Does that help? I have suspected the carb but don't know if or how it can be adjusted. I have an inline shut off and run the carb dry after every use.

My mower suddenly revved up past throttle set speed then blew out a ball of black smoke and died. If allowed to sit for a bit it will start again, run a bit - enough to get the oil hot I would say - then repeat the cycle I pulled the carb off and made sure there was nothing in it blocking it...
