What about the triangle? I have a bunch of different answers from different sources.

| | | | | Joined: Feb 2009 Posts: 128 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2009 Posts: 128 | It is a 235 on a 46, so it might not be the same. The engine is really close to catching, but it seems to be off just a bit. Should I try turning the dizzy so the rotor is just hit the #1 spark plug at TDC? It's soooooo close!!!

Be careful, if it starts backfiring, go in the other direction.

Leave the throttle in. | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | When initially starting and not knowing if it's in time or not I get it as close as I can (TDC, points open, rotor points to #1). Then while cranking the engine and with the clamp on the distributor loose turn the whole thing one way and then the other, somewhere in there it will fire and run, then adjust timing by ear and lock it. Once running you can set it any which way you please, be it a vacuum gauge, ear, or timing light.
On a first start you will probably choke it some, and no throttle other than by hand/foot as necessary to keep it running (when starting never use the throttle cable on the dash). You'll need to judge if you've choked it to much or not and try not to flood it.
Check oil pressure immediately on startup, shut it off if you don't see any in 5 or 8 seconds or so after starting.

I had a feeling it was going to be a late one, but it paid off. Tomorrow I will check for oil pressure. Should I just take the valve cover off and check for oil at the heads? I can't believe it's finally running. Only ten seconds, but it's running!

Good luck,and sounds like You're having fun,

By the time oil gets up under the vavle cover, you could all ready have wiped out the bearings. Is this a new rebuild, if so, don't let it idle for long, get it started, set the timing by ear and let it run at high idle to break in. 10 to 15 minutes is a good break in, don't let it get hot, have a garden hose standing by to cool the radiator, once the time has passed, slow it down and set the timing and idle speed.
Glad it started, now install that oil gauge!

Heed Joe's advice.
| | | | | Joined: Feb 2009 Posts: 128 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2009 Posts: 128 | Alright guys, oil gauge it is. Where exactly do I connect it. I am new at this and it is a fresh rebuild. I assume it connects to the port where the actual gauge cluster oil gauge connects? What should the pressure read?Thanks again for all the support.
