Keep searches simple. Use keywords, e.g. "leaking", "pump", "broken" or "fit".
Engine quit due to valve guide sliding out causing rocker arm to be immovable resulting in bent push rods.
Clean engine with a Gunk type product. Remove valve cover. Loosen bolts and remove old cylinder head. One bolt is located inside valve cover area. Remove old gasket and inspect and clean that surface. Attach new head with new gasket using existing bolts. Torque to 18'#s with a cross type pattern. Attach new rocker arms and push rods. Set valve clearance to .004 - .006. Attach valve cover with gasket. Check oil level. Start and let it warm up. Let cool remove cover then check valve clearance again. Replace cover.

Bad governor
Look on YouTube for video's on how to replace a Briggs governor. There are several there. My favorite, with best explanation, is, "Easily Replace Briggs Governor Gear (V-Twin Intek Engine) with Taryl". https://www.youtube.com/watch?v=wn3eanGxSEA&t=152s.

Taryl (probably not his real name) does a very good job of showing step-by-step the whole procedure, along with some additional hints/tricks/techniques of value.

Not including oil and filter, I spent less than $50 for a new governor, gasket, and drive shaft seal. That's all that is really necessary to replace is those three parts. That is, unless pieces of the old governor tore up a gear, valve, or something else. Inspect everything! {I was lucky and only the governor was destroyed}

One word of note. Be sure to clean out all of the debris from the blown governor. Be sure to remove the spark plugs and carefully rotate the drive shaft while looking for nooks-and-crannies where debris can hide. I tried to use a magnet to help, but it didn't help much, even though the block is aluminum.

Good luck.

Rod broke ruining the case and camshaft
dissembled ordered repair parts, piston ,upper case, rod, camshaft, seal kit, and motor maintenance CD
The camshaft first provided did not have the compression release device on it and the cam lobe position was all wrong for the model engine I had. .
Parts Select provided me with the proper cam Shaft. Removed engine from mower (Scag Freedom Z) 15 minutes, drained oil, flipped upside down removed bottom case, removed wrong cam shaft, reinstall new valve lifters, camshaft with decompression release on it matching dots on crankshaft. Used paint brush to coat all parts heavily with motor oil.
Do not put sealant on case gasket,(it might change crankshaft end play), retorqued bolt in alternating pattern, placed nylon pipe tape on drain plug threads, and reinstalled engine on mower. It started instantly and ran extremely smooth with no oil burn or vibration.

I am very happy with the support and quick mshipping Parts Select provided..
