I just bought my first home and my first cub. A good friend of mine is big into cubs and on this forum somewhere

I pretty much bought one because of him. They are pretty awesome!
Anyway, I just bought a Cub 102 thats in really good shape. Im thinking its been restored once but anyway, it sat for about a year and a half. everything works great on it but the clutch pedal. Its stuck down all the way. With the help of my friend, we disconnected the brake lever and the clutch lever. The clutch snap pretty good and seems fine. But the pedal is still stuck. We used pry-bars and body weight to get the pedal to break free to no avail. Its been sprayed with PB Blaster the night I got it (last week) and again this past saturday. Im thinking the shaft that goes through the frame is frozen in the frame. The shaft on the pedal side seems to have a tiny bit of play but the shaft on the other end doesnt budge.
I kinda dont know the best way to go about it from here. Just keep spraying PB Blaster on it until it breaks free? Or should I pull the retaining pin on the inside of the frame on the pedal side and try pounding the pedal out?
The paint is pretty good so i dont want to use heat.
Help?
