I do get dodged with that as well sometimes
and sometimes tend to rebuild that old carby, but then considering the AC thing and as we intend to always run on petrol, I feel I should go for a swap. Engine is good as well, just eating up oil a bit and giving blue smoke, but runs well and starts well. Also, have never inspected other things such as plugs, wires or other important things as well. So yeah, it is a bit of a tricky decision.
