BREAK DISTRIBUTION BELT IN R-21

Hello friends:

I have followed your tips and I have mounted the draft distribution strap in its position and checking the stop that did not stick in valves.

When trying to start the engine, it makes a "broken" noise (I imagine that at least one valve), so I will have to make myself with patience and disassemble the cylinder head.

Can anyone help me disassemble it correctly? Can you tell me what order to disassemble screws I should follow so as not to deform it? Should I take into account anything else?

Also, to get the broken valves, could you tell me what steps should I follow?

As always, thank you in advance for your help.

All the best

To remove the butt bolts, just let them go up the squeeze is the one that has an order, now you have to take out the escape multiple, the admission comes out with the butt, the valves combines you more to send it has to do it to do it yourself, and to take them out it is easy but to put them and to make them is a bit complicated and tedious.
