I am putting in a new piston and crank and I can't figue out an easy way to get the flywheel or the little piece after the clutch that is on the crankshaft. Does anyone have any exper. with this, all the bolts are off but I can't get the flywheel off it's all stuck??
 
you need a puller. you can order one from DDM on the left side.

you can also go to an auto parsts store like AutoZone or the like and buy a wheel puller there. a small engine or lawn and garden shop in your area may also have them available.

once you got the puller, then you can take them off realy easily.

I have removed the flywheel (rotor), and was in a rush, I found you can quickly make a puller like the picture below if you cant go buy one right away.
Take a piece of flat stock and drill 3 over sized holes in it spaced close to the two rotor bolt holes and one in the center shaft. Use two matching threaded bolts to screw into the two holes on the rotor and use one in the center with a nut on the bottom you then can crank the bolt in and the rotor will pull free. I used a carriage bolt that had a square under it because I had no others but I would recommend using a standard bolt with a head to crank. Like I said in a rush and used what little knowledge and materials I had but it did work.:)

Now on the clutch part I have a old copy of a post I saved since I knew it would get buried. Use the bolts from your spur/pinion carrier and follow the following photos to remove;

Good stuff BtB... It's not cheap, but rather ingenuity in action. Make due of what available. I have not open up my engine yet, but now I know at least one person to aim my questions at if I ran into problem.... :)
