I have got my hands on a seized Picco engine. I am wondering how I can identify what model of engine I have so I can order some replacement barrings and what not to get it back into running shape.

any help would be greatly appreciated.

If the engine was siezed up while running then it will cost you more to repair it then it would to buy a new one.
Connecting rod, piston and sleeve and maybe some bearings as well.
You could buy another and have some left over.

I think Trinity distributes Picco parts now, not sure though.
They have a website....Look it up!
