I set the engine to TDC on cylinder #1. The timing mark is lined up with the case split. Both the intake and exhaust rocker arms have a little movement when I turn the fan pulley slightly left and right.
The distributor rotor is pointing to about the 8 o'clock position. Does this look correct? Also, how do I set the static ignition timing on this engine?  |

Both cyl. #1 valves should be closed to be on TDC compression, otherwise the engine is on TDC exhaust stroke I use a continuity tester to set static timing. Align your timing marks and slowly turn the distributor until the points break (no continuity) |

If the #1 intake and #1exhaust rocker arms are moving at/around "TDC", you are not at TDC for the #1 cylinder's compression stroke.
You could be at TDC for the #1 cylinder but you may be on the exhaust stroke, but maybe not. Reconfirm everything. Things like the fan marking for TDC (some Type IV motors don't have a mark on the fan for TDC), where the distributor is installed, etc. |

Things like the fan marking for TDC (some Type IV motors don't have a mark on the fan for TDC), where the distributor is installed, etc. I checked both the fan and the flywheel, and all the timing marks line up. I rotated the engine one full revolution, and now the rotor is pointing to the 2 o'clock position. The problem is that the air temperature sensor is blocking distributor vac. I have to remove the sensor; otherwise, I can't set the timing.  |
