While waiting for replacement parts to arrive I started dismantling the engine. Carburetter overhaul will follow once the engine has been put back together.
Top view, everything still in place.
Cam covers removed.
Some dirt in and around the water pump.
Bottom view, sump removed. The oil pump is on the right.
Timing gear cover removed. I had to grind through the bottom timing chain because the pistons are blocking the crankshaft and you have to turn the top timing chain to be able to remove the cam shafts.
With the cam shafts removed, the cylinder head could be removed and it was somewhat obvious why the pistons are blocked.
The valves. These will be replaced.
One of the pistons (the only one that came out right away, the rest is still soaking...)
