Thank for replies 
Just quick update: No wonder the old girl wasn't happy looking at the state of the carbs.
Took the carbs apart and everything was completely covered in green gunk and that hard to shift varnish type substance. The jets were mostly blocked, gave everything a good clean with carb cleaner then took it to my parents next door neighbour to put the bits from float bowl and jet needle side etc in his ultrasonic cleaner. We did this one carb at a time so not to mix up parts. Not sure how but managed to lose the small spring that goes on top of the jet needle. Can't find spares so had to rob a spring from a biro pen and cut down to size, it only holds the needle in place so it doesn't move.
After ultrasonic cleaning everything had a good gong over with carb cleaner and a toothbrush, and the jets were cleaned out with proper jet cleaning files.... different diameter metal rods. Amazing how much green gunge came out the little holes. The carbs were cleaned with some "gunk" and a toothbrush then had a good going over with carb cleaner.
Just ordered some new float bowl gaskets and a fuel filter so all the bits are in seperate labelled up tubs. My dad had the other seals, good job as they were knackered as well. Rock hard and starting to split. Hopefully once it all goes back together and I clean the tank breather hole out it should run alot better. I don't have a carb balancer so will have to see how it is after, might have to go to the bike shop for that if needed. I know you can buy cheap balancers but not sure if they are very accurate.
Next door neighbour who fixes up lawnmowers and anything with an engine said he has never had so many issues with carbs since they went to ethanol mix fuel. He basically said if you use standrad fuel then use a fuel treatment with every tank, and if not going to be running for more than a month or two put high octane petrol in the tank first. I think Esso go faster juice is supposed to have no/minimal ethanol in it.
