hi guys, i am rebuilding a major but need help with checking the fuel pump timing. the serial no. of the tractor, stamped over the starter motor, is 1331993. the pump is a simms SPE 4A 75S 498 and currently the fly wheel is showing 23*BTDC. According to my workshop manual a major with this serial no. should have a simms SPE 4A 70S 296 (or 380) and timing mark should show 26*BTDC. i have the head off and i bought this tractor recently as a non runner so i havnt heard her run yet. I"m sure that various parts are not original to this tractor, probably including the pump but can anybody confirm the current timing settings with these details??
