Kostas. Good find. The carb kits are easy to come by. Tillotson HS series, Kit is RK-23HS.
If it does have a worn out filter look at this post as they are rare.
Some good ideas from Modifiedmark, OhioGregg and Warped5 on saving the filters

You should be able to make gaskets if you need to. I have a tracing of the oil pump gasket if you need to make one of those.
I don't have a 4200 IPL but unitl you can get one here is one for the 5200 which should be pretty close.
Did you get your parts? If not, they are likely still on the ship.
