First stop for me would be Your plug gaps one may of opened or closed to much. After that I'd check the dash put oil if low check the diaphragm for damage before topping up. Hope this helps

Are all the leads on correctly?

Hope this helps SU's don't have diaphragms but I would agree in looking at the ignition side of things before you get to the carb Is it spluttering on acceleration? a top up of/ using thicker oil in the dashpot helped on my MGB when I had some spluttering and hesitation on acceleration |

Checked all the leads while it was running and it was down a cylinder so tried a differant lead and it was still the same so i pulled the plug and it was fouled up .
Gave it a good clean and van fired a lot better took it for a run and by the time i got to work it was running great again thanks

Good point I'm hoping months of being started on the drive and not going anywhere was the cause but definitely going to keep an eye on the plugs as I put some miles on it
