Jeffie8696, if your problem is what engines to give up in case you have to move, let us help you decide which ones to give up. To compensate us for this service, you can send us those "undesirable" engines.
I don't have as many engines as most of you. But the brands I have/had are: Irvine, Supertigre, OS 2 &4 stroke, Norvel, Magnum, Thunder Tiger 4stroke, Siato, and Fox. I love them all, even the less exotic, expensive, or powerful ones. They all have a story. But the one I would never give up is my 18 year old Irvine 40 ABC that my wife bought me for our first Christmas together. It is the old 2-piece crankcase and awesome carb. I put a tuned muffler on it and performance is stunning. I can run any fuel through it without having to tune excessively. I usually run the old fuel from the previous year through it and it has no trouble. I can run a 12x4 prop with no fuss. I call it the "honeymoon" engine.
