We're supposed to guess.
I'm guessing (s)he's got a push mower, and (s)he is referring to it as a pull-start.
Then, I'm gonna guess it's leaving scruffy spots in the yard.
Then, I'll suggest that you sharpen the blade.
See? Problem solved! Thanks for posting!
BTW, no need to move a thread when a question hasn't even been asked.........
I've seen newbies start vague threads in the past, but this one takes the cake.
