the compression release lives on the cam gear. There are two cams depending on when the engine was built. One is NLA and the other $123. The other alternative is to buy a new motor for it. The cam is not all that hard to replace, pull the engine and then the sump. Put everything back together. It is like 8 or 9 bolts. Then adjust the valves when done. If it is laying on its side, the lifters won't even fall out. If they do, keep track of where they came from. Might have to replace the sump crankshaft seal too if the rust on the crankshaft damages it. Hardest part is scraping off the old gasket and cleaning the sump cover. Date code is on the engine. It reads YYMMDD-factoryID The serial numbers are not numeric when ordering parts. An engine that starts with say 11 was made in 2011. An engine starting with 99 was built in 1999. The 11 number is newer than than the 99 even though a serial reading 990612XX might seem newer than one reading 111203XX.
