Hi, lads can you help...just installed a recon pump(19j), but landy will only run with top bleed screw open, it will idle and rev as normal until this is closed, then die. have tried holding throtle open fully and then closing the screw it will run but as soon as i move throtle she stops ! is there air in the pump still ?

First of all :welcome2:

Is this what you have got? If so, was it set up before you fitted it, or are you starting from scratch?

yes the same engine...i took the pump off had it serviced by a specialist and put it back on, changed the boost diaphram,and bled the pump, but i dont seem to get alot of derv at the injectors, but open the samall 8mm screw on the top and turn her over and she starts as she used too. but with derv running out of this screw

OK. At the front, in front of the bleed screw is a spring-loaded adjustment. That is your tickover thingy. If you screw it in a quarter of a turn, it should allow your engine to start and tick over

Don't touch any of the others yet!!

Try a bit more, and if you can see any smoke from the exhaust, what colour is it?

on the first attempt earlier as i said it started, ran for a few seconds then stalled, (white smoke), all attempts after that it would not start.....undo the bleed screw and she starts after a few turns and while running no smoke,( with fuel leaking from the bleed screw)..... could it be over fueling and flooding, while running all seems fine.... idle, rev, smoke all good, close screw and it stalls
