So found a likely candidate, a 34cc Briggs 4stroke trimmer engine. Cute little oil in sump flat head. Weighs 8lbs. Not cheap at a 100 bucks but seems to be viable. Will start a thread if I go this way.
BikeBerry has replacement parts for the BT80 in stock now. Are fairly reasonable $$. They have the recoil but don't believe I will bother with it.
