I've found a few blower /Vacs lately if your still after a motor ,the Ryobi RGBV3100 blower vac below starts easy but compression is only 40 psi and I have a spare line trimmer motor that's on 50 psi but you usually loose 10 psi with the long hose comp tester.
They will go into scrap if they aren't wanted , the blower vac has a loose fanwheel ,It looks like $11. to post a bag with up to 5 kg so could put the motor in with a spare barrel and piston.
