Hello, I'm in the process of putting together a GWS Win Wind, and need some advise on installing the engine (all my other arf's had the holes pre-drilled). The engine mounts were already installed and the recommended engine (OS 40 LA) fits perfectly.

I am going to use screws and nylon lock nuts... but my main question is--> When drilling the holes, do I make the holes big enough for the screws to slide through or do I want to have to make some resistance for the screw to go through the engine mount ?

Also, can someone recommend the proper size screws, nuts, drill bit etc... ?


Thanks, NJF72
