Supply of used engines for sale

I don't build these bikes but do have access to a supply of used engines from - untested, as is etc. - just wondering if there is a market to sell them for anything other than scrap. The scrap value of these engines is $2.00/each and I'm willing to stockpile and separate them for any reasonable offer. Again, as is where is cash sale. I can probably supply 100/month or more to start.

100/month Yes - 2 stroke weed wacker engines - all different manufacturers and conditions.
