Combines 85 f 3 injection pump timing

JR, Depends on the serial number of engine and if it is a 433T or 433I engine. On the 433T and the serial number is between 33-00466 thru 33-02762, the timing should be 16 degrees BTDC. If your engine is a 433T with serial number 33-02763 thru 33-05864andup the timing should be 18 degrees BTDC. If your engine is a 433I and the serial number is 33-00466 thru 33-02762 the timing should be 16 degrees BTDC. If your engine is 433I with serial number 33-02763 thru 33-05864 and up the timing should be 18 degrees BTDC. Hope this helps, Hyper Harvest II
