Best practices for setting timing and adjusting carb.

[rickv100]

I have copies of TM9-840 but do not have the military ignition adapters or gauges. I have standard 12v timing light, tach and dwell meter.

Points have been set and adjusted to gap per manual.

Should I also pickup a vaccum gauge to tune the truck.

Looking for some general guidance on setting timing and adjusting carburator.

Thanks,

Rick

If your truck is 24v you can use a seperate battery to power your timing light. You can make or buy a short ign wire to put between the ign cable and the #1 plug if you still have the original water proof plugs. This will work with the inductive pick up for the light and the tach. When I had points ( I have replaced them with pointless ign) I static timed mine with a piece of tissue paper/cigarette paper between the points and set the timing marks on the front pulley and rotated the distributor until the paper just slipped out of the points. When I checked it with a light it was right on. SO if you prefer you can time the engine that way. SO move the front pulley in the direction of running( bump the starter and you will see the direction nice thing is you can just pull on the foot lever from under the hood), Pull the pulley up to the timing mark, DON'T BACK IT UP. if you have to back it up go back at least a 1/3 of the pulley travel and pull it up again. Move the distributor until the paper slips out from between the points.
One last point if you disconnect your distributor vent lines moving it is much easier.
Hope this helps
