Cylinder

The fins on the cylinder were absolutely stuffed full of thick muck & tarry gunge - the engine casing was also coveered in the same stuff. Horrible stuff to get off, like a mixture of thick tar and fine sand. The fins on the cylinder casting were filled up - cant have been much cooling due to airflow at all, possibly a contribution to the engine siezing up?

Been scraping bits off now and again over the past few weeks and its getting a bit cleaner. attacking the cylinder vanes/fins now with a small screwdriver and a kitchen knife, - its slow going.
Just hope its going to be fit to reuse when cleaned up.
Removed the crankshaft - covered in black gunge, - but seems alright - just a slight bend in the con rod, -in the vice and gave it a clout with the hammer - seems ok now!
