My son (who lives out of town) has a Honda 4.9 hp snowblower HS622.
GX160 K1.
He's trying to change the oil and has run into a bit of a snag in that he has removed the plugs from either side AND a mistery plug from the bottom.
He's getting conflicting opinions as to what lube goes where.
Pretty sure it's oil in the 2 side plugs (what weight?), but what about the bottom plug?
Many thanks.
