I recently went to JB to see this mechanic who specializes in taking carbs apart, wash them in kerosene/diesel and tune them to the car. My regular mechanic got me the repair kit only which explains the "Made in England" seals.
What a freaking difference! Previously the car gives me 12.9 to 13km/L and now she is giving a whopping 14.9km/L!
Power to match as well!
