I need help. I have a annoying flat spot in the ruining of my defender 90 (which has a Disco engine & box )
this happens when you start up & then rev up it's very slow to rev @ start up & when reving down it nearly stalls then picks up again.
New bits fitted so far are fuel filter,new diaphragm in main fuel pump, New lift pump & new pipe work. Now I am at a lost as to where to look or
what to fit if any thing to replace come on guy's & girls help me out.
