RE: Weedeater porting question
Roll,
That looks exactly like what I have, except the cylinder. I have the 4 bolt, spring muffler, and 2 bolts for the cyl to crankcase, but the cooling fins are deeper on mine, and one side has notches for the bolt, while the other has holes large enough to allow the bolt to be withdrawn through the head. Yours appears to have a larger bore, but about the same outside dimensions to the fins. I bet mine is the 18cc.
