Rebuilt engine starting problem
Hello, let me first add that this was the first V8 that i have done much at all with. Its a 302 in a 71 stang. I also havent worked with a car that doesnt have coil packs, as where my questions start with the distributor. The engine was taken out of the car, overhauled and put back in. I wired it all up to the best of my knowledge. It gets spark on every one of the plugs, i tested to find this out. I had touble following the plug to dit cap setup, because my cap/dist seems to be different and wont spin so the cap clips are at an angle like in my manual. I got all 8 wires on correctly and they get spark. I turn it over( by crossing the solinoid) because one of the other wires are effed up somewhere... errr... So, i turn it over and it doesnt fire, i spin the dist clockwise and it pops, i spin it more and it pops a few more times and the diaphram bottoms out on the intake mani. ( i turned it almost 90*) It was getting closer to running the more i turned it till it bottomed out. Ive never dealt with anything older like this, as everything else ive worked on is newer technology. I figure im doing something simple wrong and im guessing some of you have made the same mistake and can help me, or give me some tips on how to set the DIST so it runs! Thanks, -Jon

Can you explain a little more? if i changed the dizzy 180* the diaphram would be pointing backwards. And, what does he mean by haing it top dead center. Ive never done this! Do i put it to TDC then put the dizzy in facing... um?? straight out? Anyone got a how to??or a how 3 because im lost. -Jon

I'll try to explain. Remove #1 plug (front passenger side) put your finger or thumb over the hole. Bump the engine until you feel pressure, at this point STOP. With a 15/16" socket, short extension and ratchet, slowly turn the engine to TDC. At this point, the distributor rotor should be pointed at #1 tower location on the cap. If it isn't, you are not in time. Remove the distributor, turn the rotor to point straight back, and with the vacuum advance pointing forward, carefully insert it. If it doesn't go all the way down, bump the engine while exerting a slight down pressure. After you have it in, turn the engine 2 revolutions and recheck your position, if you are good, then back up the engine to around 12-15 degrees BTDC, then bring it slowly to 10 degrees BTDC in the normal direction. At this point, move the vacuum advance counterclockwise, turn on the key, and slowly move it clockwise until the points "pop" at this time you have just static timed your engine. Firing order is 15426378 with 1234 on passenger side and 5678 on drivers side. If everything is good, it should start immediately. Good luck, PM me if you need more detail.

• INSTALLING DISTRIBUTOR AND TIMING ENGINE
NOTE: Before installing your distributor, check the gear drive
on the distributor and oil pump for any signs of wear. If worn,
be sure to replace with new or you may wear out your
camshaft prematurely. This is especially true when rebuilding
your engine and a high performance oil system is used, which
generates a heavier load on the camshaft gear system.
1. Turn the engine over in the direction of rotation until the No. 1
intake valve closes and continue until the pointer on the front
cover is approximately 5 degrees BTDC.
2. Re-install the distributor with the rotor pointing towards No. 1
terminal in the cap, and with the vacuum advance canister in
its original position.
3. Lightly tighten the hold-down clamp so that the distributor can
still be turned to determine final setting using a timing light
with the engine running.
4. Replace valve covers, carburetor linkage and remaining vacuum
and electrical connections.
5. Re-install air conditioner, if so equipped.
6. Re-fill radiator with coolant and re-connect battery.
7. Double check all connections, fuel lines, etc. before starting

RE: Rebuilt engine starting problem
i had the same exact problem on my el camino i have......
everything looks rights as you stated.....but the dist is 180 off....
one thing to check before you try to much.....is gas going in the carb ??? that could be the problem.
But if you have cranked this moter over alot and gas is going into the carb..... i would pull out the spark plugs and crank the engine over once or twice to blow out any gas that has built up in there....and then let the engine set for a few hours to dry out. If you dont you have a good possability that you can litleraly blow up the moter.....it is very possable...
just becareful..
