We all know the boxes these are mounted to are flimsy. Especially the top piece where the engine mounts. I feel like over time it could break. My solution was to glue 1/4" plywood onto the top piece from the inside of the box. I had to route out the new piece a little for the ignition box. I replaced the mounting screws with longer ones. I Also used some dense foam as a bettery holder. Cheers
