Bowie69 Posted July 23, 2015 Share Posted July 23, 2015 Sounds like the carb is leaking fuel from warpage, very common and no good ones available now.... if you aren't a stickler for originality and can wave a welder around you could fit an SU and having running wonderfully.

Josh NZ Posted July 23, 2015 Share Posted July 23, 2015 Spray wd40 in/around the air intake joints and if it revs up you have an air leak somewhere Quote Link to comment Share on other sites More sharing options...
Gazzar Posted July 24, 2015 Share Posted July 24, 2015 Check the advance diaphragm, they can go religious and let fuel through. G. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted July 24, 2015 Share Posted July 24, 2015 As previous poster suggested best solution is an SU , better mpg, and response , The carbs fitted to landrover series never were much bottle, although some were slightly better than others.
