Yes it can bite your engine innards, but heck my first Combat ingested a thumb nail size piece of carb slide and ran great for 1000's miles like that till looked in to see all the peckering and Amal reason. I just nip up real hard as don't want to fight the loctite taking back off. Warning experience noted and properly pensive again.
Just don't seem to be any easy shortcuts, labor savers, to keep Commandos intact.
