so i have been out tinkering with the carb. i moved it yesterday, under its own steam for the first time in months, and the throttle has a dead spot. if you build up the revs steadily then its fine but if you just put the throttle down it wheezes and dies. i am not sure if its not getting enough air or fuel though. i did the usual trick of spraying easy start around one area at a time and listening for a change in engine tone which would point to an air leak, but i got nothing. then i tried using the priming bulb at the same time as revving to help along the fuel but still came up with nothing.
if i build the revs up then its ok, and if the revs are already up enough then it picks back up with no issue. its just coming up from idle. building up the revs can be done relatively quickly too, but you cant just put the boot down and let it catch up.
the timing is fine and the ignition is new right through.
any suggestions? i am not great with setting this kind of thing up yet as i have mostly had diesels and its been a long time since running with a petrol.
