Removing head shavings from cylinder?

[metal-chicken]

I've just had a timesert fitted to repair a damaged spark plug thread in my BF225. Repair has gone well but I could see some aluminium head shavings in the cylinder when I looked using my cheapo usb camera.


So far I've adapted a drinking straw to fit my shop vac and managed to suck out a good pile of shavings and I'm not sure there's anything left in there. Is there anything else I can do to get the last few out short of pulling the head?

At tdc try blowing compressed air in to loosen remaining shavings making sure piston does't move and vacuum again

Yep, did that. Sucked with a shop vac, blown compressed air (small tube which got right into the cylinder), sucked another 3 or 4 times - think we're good, turned it over without plugs in. General wisdom seems to be that aluminium shavings, although not ideal, don't pose too much of a risk as they'll get blown out or just burn up.

Job done now, everything buttoned back up and had a good test run in the water tank.
