Help with HX number & running rich

Jeep Information

So, does anyone know for sure if that 1st number is a 5 or a 6 on the HX number? Im thinking 6 because of the way the 5 in the cast number below it, but I can't find any HX number examples to compare it to. Having trouble with it running rich and have replaced everything I can think of to replace. Need to find out if maybe this isn't the original motor for my 95 YJ and if that may be causing the motor and the refurb ECU that I put in to not play nice with each other. Any other helpful input would be appreciated!
