Hi Sajeev,
I have a 1990 Mini Mayfair 998. We’ve owned it since 2017 when we imported it from Japan. When we first got the car we ran through it and got it running fairly well. We’ve put approximately 5000 miles on it since we’ve got it. Over the last few months it has started running rough with some misfires. After checking the plugs, carb, and timing I’m suspecting that the valve clearances may need adjusting. My questions:
What are the signs that a classic is in need of checking the valve clearances?
