Engine Problem 49cc 142f

Hey fellas! I'm very new and very unskilled to this. The problem I'm having with my 142f is this... The engine fires up and idles/revs just fine but when there is a load on the engine, it shakes violently. The engine has <100 miles on it. My neighbor though it might be a damaged crank shaft but my technical skills are limited. Any thoughts?

Edit: Found a bolt head lying on the ground... upon further inspection, a bolt on the side of the engine mount seems to have broken off. Going to mend this and see what we're working with.

Edit2: Having replaced the bolts with better quality ones on the engine mount, it still shakes when a load is on it.
