New here so I hope I can get some help.
I have an Ariens mower that is a couple of years old and has been running great with no problems until two days ago. Engine won't spin fast enough to start , just lugs.
had the same problem with an older mower and it was the valve adjustment so I thought that was the problem. The motor is a 310000 model and the spec call for intake valve to be .003-.005 and the exhaust to be .005-.007. So I set the intake (bottom) valve at .003 and the exhaust (top) at .005, spun the engine several times by hand and rechecking the clearances each time. They were at the correct setting.
Thought it may be the battery even though my son put one in this year, battery read 13.1 volts at the terminals but when i checked the voltage at the starter it read 7.6 volts. i used some jumper cables and hooked the mower to the car and it lugged for about 1/8 turn of the flywheel and then started spinning and fired right up. I am now leaning more toward a weak battery and wondered if anybody else had experienced a similar problem.
Thanks in advance for any input.
