cars been stood a few month when u start it it kinda thumps n judders as if the choke isnt pulled out when u put foot down it still does it only faster it still the same even when warm

poured fuel down carb when running made different change plugs n rotor n diz cap still no diference

do u think it could b seized water pump or may b piston rings

Sounds like a confusing one,

do the revs die when you set off?
did it have a service before you left it? maybe the timings belts out
does it back fire?
are the Ht's connected in the right sequence?
did anything happen before you left it? maybe the camshafts bent, or somethings not sitting right in the cams area :?

It wont be your fuel pump, your engine wouldn't start at all, i wouldn't imagine the water pump because its mechanically driven, have you checked you haven't got a knackered dizzy? other than that i'd think its your cams :?

dizzy is mechanicly driven 2 though so how can it b knackered its had new cap an arm

i was thinking maybe it could b a stuck vavle but would engine still run if it is , by run i mean u can lean lean through window turn key an it will idle well its more of a thump than a tick over

or could it b fuel related carb or pressure

its a j reg 1.4 sr on standard pierburg carb

standard filteri was thinkin maybe the carb
if a vavle is seized will it still start up with out having 2 give it throttle
