1st time starting issues
Today was to be the big day that I start the newly rebuilt engine.
Here are the pre-steps that I took:
1) Set the TDC mark on balancer with the 0 degree mark on the timing tab. Verified that I am on the compression stroke.
2) Installed the distributor such that it settled in with the rotor pointing exactly at the #1 post on the distributor cap.
3) Poured in a few ounces of gas into the carb.. Put about 1.5 gallons into the gas tank.
She cranks over strong but will not start..She spits out at the carb when cranking as well.. And she is getting spark...
Just trying to avoid too much cranking and no starting...Any suggestions?
thanks Rob

Well no luck with that either...I tried rotating it quite a bit in both directions while my buddy cranked away and it just seemed to spit out gas. Does the fuel pump need to be primed? I have been adding gas through the throat so I am not sure if that is what it is spitting back out.
Any other suggestions?

If the carb is spitting fuel, then the fuel pump sure as heck is pumping! So don't worry about that end of it, just make sure your spark is timed right.
If you are getting fuel and spark, then you should have SOMEthing even if it's a backfire through carb or exhaust.

Yes- I guess that you could say that I am getting a backfire through the carb. The fuel tank may have had a little old gas left in it before I added the 1.5 gallons to it. Perhaps it won't start because of some old fuel?

when you pull the throttle linkage is the accelerator pump squirting gas? that will tell you if the fuel pump is pumping gas. if you are just puoring gas down into the carb then you are most likely flooding it.
put a timing light on it while cranking it over to see where it is at.

While you are SLOWLY turning the distributor, make sure that your cranking buddy isnt constantly pumping the accelerator. And dont keep pouring gas in the engine... If you flood it, it wont start regardless of the timing.

You say it is spitting out of the carburetor. As previously suggested, confirm the valve action at number 1 cylinder in relation to the distributor.
As well, while you have the valve cover off, check to be sure the valve lash is set correctly. If the valves are too tight, holding a valve open, it could spit through the carb.
PS; don't ask how I learned about valve lash during a rebuild!

When you say verify the valve action on #1, what am I looking for exactly when I pull the valve cover? Should I be looking at the valve springs on #1 when it is cranking?
Also, I have rotated my disti. so much that I am not 100% where I originally had it to start with now .. Thanks - I'm a little new at this.

Like 79vetter was saying, with the valve cover off, slowly rotate the engine watching #1 cylinder’s intake valve as it begins to open and when it starts to close start looking at the timing mark on the balancer and align the engine at TDC. This is the compression stroke for #1 cylinder and the distributor needs be installed with the rotor pointing to #1 sparkplug wire. Also check for proper sparkplug wiring. Starting from number 1 and working clockwise should be 1,8,4,3,6,5,7, 2.

I am sure you did but when you connected the timing chain to the timing gears the dots on the cam gear and the crank gear were lined up? If so it has to be the distributor timing is way off. Another thing that could be a problem do you have your rocker arms too tight causing a valve to stay partially open causing firing thru the intake?

i'm unsure of what you mean by the distributor being 180* off.
if the engine is set at tdc on compression stroke and dist wire and rotor are aligned to #1 cylinder, how could the dist be 180* off?
thanks
