Yes the motor is very hard to turn by hand past the compression stroke. The valves seem to only open and close in their normal fashion, i do not observe an additional opening to relieve compression. Pretty sure my compression release has failed.
As far as parts go, looks like a case gasket and the cam/lifters is about all i would need for cam replacement?

Another thing that I would add to the list that is of utmost importance, and I am sure some people will argue this, is the Briggs service manual for this engine. Single cylinder OHV Manual Part# 276781. The book will have all of the necessary information in it. Torque specs and tolerances. There is a chance too, that other damage may have been done inside the crankcase when the compression release failed. If you can envision the the engine running at approx 3,600 rpm ( assuming that) and a small piece of metal being thrown into the mix, it's like a pinball game on steroids. Just something to keep in the back of your mind. I would get a manual, pull the engine, disassemble, inspect and make a parts list, then order the parts, and repair. Just my 2 cents

Hi try this drain out all your old petrol, petrol goes off after 30 days. Have a look at this!

Just curious, I mean no disrespect, but what does gasoline have to do with an engines ability, or lack there of, to properly cycle? Assuming that gasoline has not filled the crankcase.

I finally got around to tearing the motor down. Everyone that guessed the compression release on the camshaft was correct. I found the broken arm in the sump. So getting a new camshaft ordered. I also found that my intake pushrod had A LOT of wear about an inch from the end. Other than the pushrod, is there something else I need to replace while I have it apart?
