hi Guys again
i did report last week i had " picked up a bargain " non runner in germany last week for under 1000 eur with 14000 mi 20000 km full with clean oil and not run for ca 6 years ( kept dry garaged ) by a older fellow ( even older than me)
i have de- varnished the carbs and they work ( i used them on my other bb on a side by side test )
tank is not rotten thank the gods gas is rinsed out and renewed
i found that the petcock had frozen closed ( rotten seal ) but i have another and it works and is installed
oil light extinguishes right away on turning over

so im now getting to the point of wanting to do a trial start
but
i took out all the plugs and turned over the engine using the starter
there was a light( not thumping ) metallic knocking noise coming from the starter area as it turns over
there is a decent spark
i did a trial turning over with the plugs back in and its the same , perhaps a bit heavier
i was wondering what this might be and wondering if i need to do more investigation before i try to light her up and possibly b--er something important up

questions
do these engines snap piston rings when they are left sitting for some time
do they snap cam chains ? interference engine...
do the starter clutches make a knocking noise if on the way out?
or ?

if so then i may need to do a valve cover off and compression check to see if the internals a b---ered
thanks for your input

Compression check should give you a heads up on a broken ring. Cam chains are pretty bullet proof. I don't think the bird is a zero clearance engine but again compression test will tell you.
The other possibility is the starter gear is knocked. You can pull the stator cover and see both it and the starter gear if you need to be sure.
