I have 2 ryobi 31cc engines that I want to take apart and get the best parts from both of them. The problem is that I can get the square shaft clutch drum off. I did everything that deacon said to do, took off the spark plug and filled cylinder with rope. That worked but I just cant get the screw out, I took a slot screwdriver and put some vise grips on it; once I had the screwdriver lined up I twisted with all my might. Nothing
The one on my first engin ecame off just fine, I'm not sure what the problem is?
