Just a hint:
Several you tube videos about how to first check and adjust the valve lash on that Single cylinder Briggs OHV Intek engine. (a picture is worth a thousand words)Watch more than one.
Note that the valve lash is adjusted when the engine's piston is 1/4 inch past TDC.
Also instead of immediately messing around adjusting the INTAKE valve lash (the ACR is on the INTAKE valve) if you find it too be more than .003-.005, if for example you find it to be .008, just locate a .005-006 feeler blade and slide it under the rocker to reduce the valve lash to .002-.003 (without loosening the adjustments)and hold the feeler blade under the rocker and try cranking the engine over with the spark plug re-installed, BUT leave the plug wire off so the engine does not start. If it still hangs on the compression stroke you then know you are just wasting time adjusting the valve lash to minimum specs. If you have to go to .001 lash or less to for the engine to crank the ACR is broken internally.
The ACR is not operating.
If it cranks over ok with the feeler inserted set the valve lash to specs and then install the valve cover and the spark plug and crank test. The engine will crank over little bit harder when spark is introduced.
I've seen some of them Briggs 31 and 33 series engines that the valve lash on the Intake had to be .002--003 for the ACR to operate when the engine is cold. They would compression lock at .005, especially on a cold engine on a very cold day. I suspect this is due to a worn ACR not opening the Intake valve open quite enough and the valve lash being just little bit more on a cold engine. I would have to set the INTAKE valve lash to a very snug .003 to get good ACR operation.
