Engine Orientation

The KAVAN AP06 can be orientated in any position on the firewall. For optimum performance the engine should be mounted either upright or rotated 90º to the side if necessary. Keep in mind that if you mount the engine inverted, carburettor adjustments will need to made differently and the fuel tank may need to be lowered. (See tank size and orientation to carburettor on next page). Engines mounted inverted tend to run richer during idle and transition to full throttle and generally are more difficult to setup.
