Briggs & Stratton 24 HP thrown push rod - new thread

Hi All,

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!

Well a lot of people have cured the problem for the cost of a head gasket. I have the fix. Actually, with one fix, you don't even need a head gasket.

You probably needed to clean your cooling fins, cooling shroud.
