Tiling Question

Can i tile over very thin patches of adhesive left on wall or do i need to prime the wall first?

I have removed the tiles in my kitchen. The walls are mainly plasterboard with skim of about 1/8 inch. A small part in the corner is ply wood. I am able to get the remaining tile adhesive off fairly easily using a heavy duty 4 inch scraper. I am finding there are very thin patches of adhesive left on the wall. They are so thin that they do not affect the level of the wall in any way. Can I tile over these or do I need to get them off or do I need to prime the wall first?
Thanks Albert for taking the time to give me valuable advice. Much appreciated. Mike

If the surface is fairly flat then I would leave it you could always use a deeper knotch trowel, but I would prime the walls using SBR such as Bal bond. Do not use PVA as this is inferior and is not fit for this purpose.
