Ok, so spoke to the garage this morning about the carbs and he assures me they were taken out and cleaned.
Although he did say that he used a different type of solution which doesnt clean the outside? (strange) but somehow cleans the inside??
I told him about the rough running and the poor idle and he has told me to take it back in on Friday for the day and he will re-clean them and see what he can do.
I'm not saying its going to fix the problem, I just want to get what i paid for and least it gives me a s good starting point to work from, hopefully he will give them a proper look around this time to check the internal parts for wear.
Oh the plus side, reading up on some of the info on the forum atleast gave me to confidence to attempt to remove my old "Ross M1 Immobilizer" which has been giving me trouble for a while and although it was a spiders web of wires, i took my time and got it sorted.
