If you’re new to working on Bugeyes, you have probably come across a bolt where none of your sockets fit quite right. That’s because they used British sized “Whitworth” bolts. They can be found throughout the car, and can cause a hassle if they get rounded off, so we are happy to offer the most popular sizes here, select one or both.

The Jets on HS2 Carbs are whitworth, we have wrenches for those here.
