Currently in the middle of restoring a couple of Orion's and one of which is my brother's first car which is a 1.4 equipe. Both cars have stood a long time and the 1.6 was last on the road in 04,starts fine but sounds like a bag of spanners.

So just wondering what parts are recommended to be replaced and what jobs i should do with them standing for sometime? they're both carbs.
Thanks
