Hi Glider,
I am back in the UK. Today I had a chance to look into the engine.
What i found is that;
1. The cam looks okay, dot to a dot if you know what i mean.
2. I removed the carburator and it looks like too much air is coming out when crancing - but this is just the imresion.
3. When i removed the gas inlet and had a look into the hole when i was cracking the engine i could see the flash - coming from the spark. The ignition is set up properly, to fire at TDE, So, to me it looks like the inlet valve (actually both of them, on the front and rear cylinder) is not closing properly when it is in TDE. It seems tha it is still open when it should be closed.
Please advice how to regulate the valve.
Let me know if you have any other suggestions.
