Mine drags and I know I'm getting plenty of power to start the engine. My mower is about 8 years old with no real maintenance done.
When I try to crank it the starter drags. turns slightly then stalls. I've been told the solenoid could be bad. I've checked my battery connections
they are good, it's not the power source, it's either the starter is bad or the solenoid is bad. I'm starting with replacement of the solenoid, the will move on to
a new starter. A mechanic that works on small engines told me it sounded like the solenoid was bad.
If you have a different experience let me know.
Simple to check.
Run a jumper from your battery - to the engine block.
Mower starts fine = bad ground
Run a jumper from your battery + to the hot side of the solenoid
Starts fine = bad power supply wire
Do the same as above to the starter side of the solenoid
Starts fine = duff solenoid
Dosn't start properly = duff starter
Before you da any of these check the valve lash.
I get a dozen "unfixable" mowers in every season where the owners have replaced some or all of the following for a cost of around $ 400 when all the mower needed was a valve adjustment.
Starter motor , solenoid, battery, ignition switch , PTO switch, Ground lead, Power lead.
