5 Horsepower Briggs Restoration Project and How to unseize pistons and valves
May be a while on the rest, just hang in there, I will eventually work on
this again, its just going to take alot of money to get it bored out and
sleeved, new valves, new piston/rings, new rod, everything! i found an old
briggs and stratton engine block with a thrown rod, seized piston and
valves. In this video i unseize the piston and valves, and remove them. And
begin the clean up process. Cylinder might have to bored. Also note, i said
on the video that i may need a new piston because of the stuck rings, not
necessarily true, because the rings should come off with no problem. Unless
the piston is scored or worn, it shouldn't need replaced. Thanks for
watching, and please subscribe!

Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem.
In this video I outline the basic valve job procedure. Cleaning the
valves, cleaning the seats, cleaning the combustion chamber and lapping the
valves in to make a better seal.
Here I cover the process start-to-finish. It's the same exact process for
pretty much all non-rotary combustion engines. It takes patience and
perseverance to do this job, but anyone can do it. Reference your service
manual for measurements and service limits. Everything else that's not in
your service manual is in this video.
I apologize for not having broken busted crap to work with in this video.
It's more beneficial to all of you when bad fortune falls on me because it
gets well documented, and many people watching these videos are looking for
answers. If you have bent valves, you will discover it quickly once you
chuck one up in the drill. You'll see the face of the valve wobble around
while it spins. You'll see evidence of this damage on the valve seat. If
it's bad, you may see damage on the valve guides in the form of cracks or
missing pieces where the valve guides protrude through the head ports.
Give all that stuff a good visual inspection. ...and if you doubt yourself,
never hesitate to get a second opinion or consult a machine shop. They
will have access to expensive tools that you wont find in your average
