Hey together, short history: My scooter started getting worse and worse, then changed (gear) oil, new spark plug, V-belts, air filter, petrol filter, Vario weights, even the carburetor I had replaced, but everything had helped nothing and got worse and worse until it came to the point that the kickstarter eventually stopped moving, really no more. Now that I was running out of a piston eater, I bought a complete set with new pistons, Bolts, rings, seals and cylinders. The package also came today, compared the cylinder optically before and then started to disassemble the scooter. When I was ready to pull off the cylinder, he refused and did not move a millimeter, I first tried to help with a rubber hammer and later went over to seam a screwdriver using the rubber hammer, but that also did nothing. I once took a photo of it. t, if the cylinder hadn’t had 2 screws next to the 4 that can be seen in the photo, I would swear the part is welded… You don’t even see where I tried to hit the screwdriver in.
