I have been cleaning up my engine bay.
I shortened all the hoses,
relocated the starter coil,
re routed some wires,
shortened/ rerouted that metal fuel line to the carb
replaced the PVC valve and fuel filter
and the one thing that was really dumb in hindsite is I pulled the distributer to get some wires out from around it and I didn't make a note of where it was pointed (stupid stupid stupid)

I cranked the engine by hand so the timimg mark on the fly wheel lined up and installed the distributer to where it is pointing toward cyilinder 1 as best I could.

When I start it, it turns over but won't light up. When I pull the accellerator wire, I see fuel going into the carb. Starter coil was nice and strong 2 days ago.

What should I check? Is it possible I have the dist. so far off that it it won't fire?

Bet you got the distributor in 180 degrees off.

TDC comes around twice in each revolution of the distributor.

It appears to only fit one way as there is a notch in the cap that aligns w/ a screw.
The vacuum is directly in front as before. How could it be off?

the rotor is 180 degrees off, not the cap... well it is the cap in relation to the rotor.

So for every rotation of the engine, the distributor rotor goes around twice?

If I am 180 degrees off, I can crank the engine by hand 1 revolution, and it should fire? Then I just need to adjust timing?

read my other post in the other thread about finding top dead center and lining up the dist. The dist goes round 1 time when the motor goes 2. The motors have 4 cycles and the piston peaks at top dead center twice in a cycle. If you are 180* off, the cyl is firing when there is no fuel in the cylinder...you are firing on the exhaust stroke

see if this works:
guess not...check this link..it shows the 4 cycles and how everything works together. http://auto.howstuffworks.com/engine1.htm

OK, it sounds like I have all the info I need to correct the 180 degree out error.

The other thing mentioned was the possibility of no power to the coil. How can I verify this? I assume I can determine this w/ my multi meter?

yup... multimeter. There are 2 wires running to the coil... ones a + and ones a -. (then theres teh spark plug wire) but just hook up the multimeter to the 2 wires and see if it gives you voltage. I forget, but it may be a switched hot, so turn the key to the run position
