Hi Everyone,

I have had starting issues with the 17hp Briggs and Stratton OHV engine in my Toro for quite some time. Battery, starter, solenoid and cables have been replaced however problem still exists. When cold, the starter turns the engine maybe half a turn and then stalls. After several attempts it will usually start. The starter cranks fine when the engine is hot.

After reading though some of the posts on this forum it appears the engine may have some form of automatic decompression system, although I am not 100% sure. Numbers from engine are 31F777 0123E1 040413ZE.

Could it be that this decompression system is faulty? I have also seen references to adjusting the valve clearances.

Any information greatly appreciated.

Andy
