lol, one of the first cars I drove regularly had a sticking throttle, being a dumb teen, I took to driving barefooted so I could use 'toe grip' when need to pull the pedal back up. When my sister told my Dad, he just came out and lubed the linkage to fix it.
ah...good times, good times...
I'm doing more of a refresh than a rebuild on my 87 EA82 and sourcing parts from eBay, Rock Auto, etc. I'm buying seals and parts anywhere I can find them because one vendor won't have it all. Mine was a running engine but had low compression on one cylinder and found it was a blown head gasket on #3. It was down about 30 PSI during a standard compression test. I hate greasy, grimy engines so I pulled it completely out to clean it all up but I will not be splitting the case or doing a re-ring. I see no reason to go that deep when I had good oil pressure, compression and no smoke.
I already did that, it holds the same fuel pressure when it successfully starts, when it goes through its shutdown phase, and when it refuses to start.
