Unc I see it says 38, read the epa label and see what it is.
OK, saw says 38cc, EPA says 42.
I've got the spline tool, but as long as I'm fiddling with the screws I might as well make slots. It'll be a while before I even fire this thing up but I'm looking forward to doing the muffler mod even though I don't really know what I'm doing. Do I make the slots or holes underneath the spark screen, or can they go anywhere?
