clutch question.

Hi all as per my previous threads my cars been off the road

For several years for an engine swap. This is now done and

Runs ok. The clutch and box were fine. Although in the last

Few months it's been sat the clutch pedal now goes straight

To the floor with no resistance. I've changed the master

Cylinder for a brand new genuine item and a new slave also.

It's bleed up alright as per manual on both nipped. It feels

Like a good clutch but start it up and it's back to square one

Straight down to the floor and can't select any gears. Can't see

Any obvious leaks and everything is tight. Can't find or hear and air leaks

Whilst clutch is being depressed with the engine running or not.

I've repeated the process about 6 times can't get any more air

Out.

Any ideas welcome

Cheers
