Well, I bought the Ryobi off the pawn shop. Just a bit over $40. Just yesterday I was hauling some trash to our town dump and found a 32cc Craftsman that seems to have good compression yet. I haven't had time to play with either so I don't really know anything about how they do or don't run. But I do for sure have one for learning to port and such on now.

If I remember right that craftsman is rear exhaust/carb and didn't have a primer that I could find. I thought that to be odd, as well as an actual on/off switch. I have something to tinker on anyway.

I have another question, unrelated to my engine quest. I have a carb from my Baja, the stock carb from the 23cc fuelie. I believe it is a Walbro 618. I know it is a touch biggernthan the 11mm recommended, but I already have it so no cost involved. Will it fit/work?
