Briggs & Stratton 24 HP thrown push rod - new thread
I am starting a new thread for this as I see there was one that spanned from 2009-2013. I have a Craftsman lawn-tractor with the Briggs Engine model 455677 - 0413-E1 two cylinder engine.
If any of you have had an issue with bent push rods or engine backfire and not starting - I have the answer for you.
Mine has had a history of bending push rods on the left Cylinder. this was caused by a stuck Valve. The only way I found to fix this is to replace the Head assembly - which I did about 3 years ago - it ran great until last week. Then same issue even though I had been adding Marvel Mystery Oil to the gas.
Yes - I just ordered another Head Assembly for the left Cylinder. It is still cheaper to replace the cylinder than the whole mower even if I only get 3 years out of it.
Really poor design by B&S!
