Any engine mounted past 90 degrees will be more succeptable to hydrolock even inadvertantly such as someone carrying the airplane carelessly With the nose down when there is fuel in the tank. Now if there is a remote glow lead and/or no through cowl access to remove the plug you have just removed the best way to clear a lock and that is removal of the plug then hitting with a starter for a few seconds.

I unless I am competing in a precision scale contest then doing the following will save a lot of lost flying and lost days at the field:

With every cowled airplane I always provide;

reasonable access for a glow driver as well as removal or replacement of a glow plug.

reasonable access for adjusting the main needle valve and without special tools

reasonable access for adjusting the mid range needle or bleed screw.

reasonable access for pinch tuning which mean an exposed section of the carb feed line through the cowl.
