whatever you do, especially if useing one of these engines in tight quarters,, don't scrimp on guards,, covers etc.
tight quarters, with narrow walkways, are an invitation to disaster, should you slip, trip or fall...
with those huge flyweels, just like a piece of cake that falls always on its icing,,, so too will you likely slip, trip or fall into the flywheel
so build up secure guards to protect yourself.
there are reasons that osha has rules reguarding area around a piece of machinery, and guards,,, it is not to make life miserable buy to
save life and limb.
