The only way the carbs can be that far over is if the motor is wrongly positioned in the frame. Standard Mk1 premier Amals. Standard R10 head. Standard manifolds. New CNW isolastic that fitted in straight up. The front isolastic comes from CNW fully assembled so no chance of spacers in the wrong place. So the motor is correctly position in the frame. So I can't see anything wrong. I have just flipped the plate and it will all work perfectly. Also need to reverse the lifting disc but that is easy with a small spacer.
