I have a webber carb on my SJ witch has been running fine for ages until I swapped engine, The new engine had been running an SJ with out issue all I have done is to bolt my carb on to that engine I have blocked all the bits my old engine had blocked off but for some reason I cannot tune the carb if I do it as it says in te webber manual I can't seem to lower the revs less then 2k has anyone got any idea its really begining to annoy me now.
