| Rambo Lambo,
Here is a way to visualise what Im on about, Lets say we are looking at a 4cyl inline motor with 2 side draughts. For the purpose of explanation the front carb is mounted right way up, the rear carb is mounted upside down. At part throttle the front carb will bias flow to the bottom of the port runner and the rear carb will bias flow to the top of the port runner. Now in the manifold change made here the difference takes place from bank to bank. I reckon the carbs were tilted to get both a straighter shot at the valve plus reduce the height and bulk of the carbs or bonnet scoop. Jac Mac. |
