AnswerHello.
I need some clarification please.
What year is this Galaxy?
"just been through mot"? Does this mean that the engine has been rebuilt?
"even on tick it runs rough" I am usnure what this means.
Has the car been sitting ? for how long? is the fuel fresh?
Has the carburetor been rebuilt and correctly set-up?
How is the ignition timing and does the vacuum and mechanical advance work correctly?
Is the timing chain good? and installed correctly?
What is engine vacuum at idle?
