What is the maximum amount of forward lean a 2 venturi webber carburettor as fitted to the 1300 x-flow engine?

If the engine is run with the block level will the carb work properly in normal driving or will it only be suitable for hill climbing?

Don't worry about it if it's within 5 degrees - once you start accelerating, braking, turning corners, etc it becomes irrelevant!

For info - my engine's level-ish, and the carb leans about 1 or 2 degrees.
