When cranking, the engine turns and there is a spark....not strong. I can't find the timing mark through the circulled(rubber) hole, but the arrow shows on the cover.
How can I freely turn (by hand) the pulley?
It is absolutely STIFF, the fan is slipping. I think I must have messed around with the timing totally.
New breaker points and distributor
Please advice ASAP.
Much appreciated.
Yes you can turn the crankshaft via its pulley.
But this is probably easier. If you want to turn the crankshaft by hand you can use a socket with a long handle / breaker bar on it to "Tighten" the bolt on the end of the engine crankshaft. Usually that bolt holds the harmonic dampener. Be careful here as if the crankshaft gets stiff you might exceed install torque for that bolt. Go SLOW. When you go slow, a bit of the compression will leak around the piston rings.
Don't forget you will be fighting cylinder compression when you do this, so go slow. If you need to do this on a repeated basis, you could remove the spark plugs, the force will got to nearly nothing.
