Static timing a TO30

Hi everyone,

Okay I have my engine block back from the shop after having the cracks repaired by bolting the block together. New bearings and seals all around and a new camshaft (I spun the nut off the old one). I am having some difficulty getting it to start though. I have static timed to 32 degrees as per my I T manual and have only got it to cough a few times. I just read in the archives that the static timing should be set to 6 degrees. Which is correct? And yes I did check the #1 piston is on compression stroke.

Thanks,

Tom

The static timing is 6 deg BTDC. The easy way to statically time it is to crank the engine over to the compresssion stroke. If you remove the #1 spark plug and hold your finger over the spark plug hole, you can feel the pressure of the compression stroke. Now tap the starter (or using the nut on the crankshaft, rotate it by hand with a wrench.) to get the flywheel mark lined up to 6 degrees BTDC. The distributor rotor should now be lined up with the distributor cap contact button for the #1 plug. If it's not, loosen the distributor and rotate it til it is. Now put the distributor cap on, pull the wire of the #1 plug, put a bent wire or a paper clip in the spark plug boot and hold it near a good ground. With the ignition switch ON, rotate the distributor until you hear the spark snap. At that point you are statically timed. Your may have to rotate in both directions but not very far. You may have to do this a few times to get it accurate. Then just tighten down the distributor without moving it, hook up your timing light and start the engine and check the initial timing and the advance mechanism.
Hope this helps you.

Thanks for the help on setting the timing. It looks like whether you set it at 6 degrees with a spark or 32 degrees with the advance it is in the same place.

The problem I am getting now is no gas to the cylinders. The carb had been off for almost two months and sitting by itself in a box. Something may have gotten into an opening and is clogging it up. There is plenty of gas in the bowl, I pulled the bottom plug and gas ran fine. I will be pulling the carb off and giving it a cleaning and go from there.

Thanks for the help. This site is always great for troubleshooting and getting answers to questions.

How do you set the timing statically with full advance? Seems like it'd take three hands. You'd have to torque the distributor shaft to extend the springs that are normally actuated by the flyweights centrifugal force. Seems like a lot of work when you can do it statically in a straight forward manner.
Did you check the shaft for radial play? A lot of these old distributors are really worn because most people don't fill the oil cup regularly. They need new shafts and bushings. You might want to check that also.

Regarding the carb, make sure that the joint where it is attached to the manifold has a good gasket and seals well or you'll have a real lean mixture and if you start, you'll run too hot. Also make sure that your float level is set correctly.
Good luck.
