initial start up-timing
So I'm about ready to start a new engine, been a long process. I just want to be sure that it fires up fast and not be grinding away. I plan on having the fuel system primed with gas in the carb. My question is with the electrical. Can I pre-set the timing and check it by doing the following...move my balancer to approx. 12 degress before TDC, turn the ignition key to the ON position, rotate the distributor until the rotor hits the #1 tower? Will I be able to see a spark at the #1 plug wire? I just want be sure that I have spark and that the timing is close to where it should be for initial start up. Hope to have it fire right up for cam break-in. Any help greatly appreciated. Thanks

Sounds good .. you can do this also if you have a multimeter with built in chime for continuity withe probe making contact at coil wire location on cap and contact at no. 1 cylinder on cap it will chime when you make the rotation of distributor housing .. also on pre initial start up you can use an old distributor shaft and variable speed drill motor to prime all oil distribution prior to firing motor .. Also be sure to find tdc by using piston stop in either direction and taking middle marking it on the harmonic balancer for good.

If you don't have the distributor in yet, pull #1 plug, pull the coil wire, stick your finger into the #1 hole, have someone hit the starter if you don't have a remote control. when #1 piston come to the compression stroke it will blow air passed your finger. Stop there. If you think you went to far do it again, and again until #1 piston is on TDC. Drop in the distributor and make sure the rotor is pointing to the #1 spark plug wire. Don't worry about the oil pump shaft if it didn't fall into place. Hit the starter and when to rotates it should fall in. Now rotate the engine a couple times with your finger in the hole and see if the rotor points to the #1 plug wire exactly when the air passes your finger. Oh, mark the side of the distributor with ink marker where #1 wire is because you'll have the cap off.

So you want it lubed under pressure, don't want to wipe out a new cam.

Seriously? What kind of multimeter do you have...and have you actually tried that?

Got her going, fired right up. Had a little overheating issue but got that resolved. Ran for about 40 minutes, varying RPM's, keeping it off idle. Changed out oil, will test and tune this week.

you've actually tried this? I've got a Beckman industrial multimeter and a Fluke and I don't think either one has the power to jump across that spark gap between the rotor and contacts in the cap.
