doesn't it say in your manual? for the Honda FG100 which is also 4 cycle,
you need NLGI#2 or some such and can get at an auto store for around 2
bucks. IIRC there is a hole after removing some parts (fg100) you squirt
it (with your grease gun) into until it comes squrting out.
I don't know if you can use the same kind of grease or not.
