Clutch/engine seized cylinder head won’t come off

[Toby woodman]

I have a new 66cc engine kit. While I was riding it, the engine started clicking and then Stalled. When I tried to re start it, the clutch started slipping. I have cleaned and de greased the clutch pads and adjusted it but it still slips and the engine won’t turn over. When I go to take the cylinder head off, only the main cylinder wall will come off. Help would be appreciated. If you have any questions ask and I can also send more photos. Thanks

Looks like he feed it too much mud and water!

Sorry I’m in the UK so I was asleep. The engine has been run with the air filter and with a good quality fuel filter. When I looked inside the air box there was mud but only on one side of the air filter. The other side which goes into the carb is clean and dry. What other photos would you like?

The piston is seized in the cylinder so I can’t get the whole cylinder off

If you can push the head back down, do so. Jam 2 nuts together on each stud and remove the studs from the engine. Now try and free the head.

I have tried removing the studs but with the studs removed the piston was still seized. maybe a penetrating oil left overnight could help to free it up?

This looks like you broke a wrist pin clip and it's jammed in between the piston and cylinder wall. If you still have a warranty, return it.

I'm just curious. Where did you buy it?
