Case 530 gas timing

Thanks for any help.

Larger Copy of Timing Chart
FROM: Case manual 9-75302
I could only use a timing light for total timing at full engine speed. The distributor would already start to advance even at a idle. Had to use test light for static timing. I"m assuming thats why the manual states using a test light for static timing???

Static & running ignition timing chart

As far as timing by ear, I've always found you could tell more by the way it starts and shuts down than by listening to it run. By ear, it will will sound happiest when it's way too advanced. Advance it until it struggles too hard starting or deisels when shuting down, then back it off a bit. Better too retarded than too advanced. Too advanced can burn pistons.

Yes I can find top dead center and make a mark but my manual does not give a dynamic specification where as I could time it by a light. Is there a general spec for this?

Then take the distributor cap off and use a circuit test light hook to the hot lead and the pin on the light to the other side of the points. Rotae the distributor around until the pionts start to break and the test light goes out.

Or do what I did , get the Petronix electronic ignition kit and a new Petronix coil. If you have your marks line up just drop the coneversion kit in place, lock it down, put the mag ring on the distributor shaft and the rotor on it, cap back on and start her up. This is a really good system, I really like mine on my 630, big sister to your 530.
