I have a murray 12.5 that I just bought from someone , used it for the last couple of months and now it won't start , it sounds like it's dragging
I have changed the oil and the gas when I got it but this is the first it's done this.
The flywheel does move and it does have oil so it's not locked up , my? Is could it be the starter ( the starter does move slow ) or the solenoid??
Or is it something else??

How old is the battery? Clean the connections if corroded (baking soda/water mix) and get them tight, and put the battery on a charger to charge it up.

Hey I just want to say thanks for the info , and it was the battery
The battery was about ten yrs old and it was dead no charge
Once again thanks , now I have to go and mow

Geeze, ten years!!
Most have a problem doing two years... that was a good battery.
