How to start a tight remanufactured engine

Recommended Posts

I just  installed a remanufactured 1967 Cadillac 429 engine that's been sitting for about two years, it crank well without the spark plugs but when I put the plug back in its tight, it turns very slow if at all.  Any  Suggestions on how I can get my motor running?

Could the starter be bad?

Maybe it cannot handle the compression. Where did it come from?

Not a bad idea to drop some oil into the plugholes and crank it over a little bit to help the oil to the top end.

There is a range of timing adjustment for the distributor. 

That range is often limited because of the vacuum advance and nearby obstructions. (intake manifold, firewall etc)

If the distributor does not get 'timed' correctly with the engine.... within that range....you can get slow cranks. 

So you may have to pull it out several times.....and mess with the drive gear slot... to get it timed in correctly with the engine.

You really cant just drop the distributor in and crank it up. You do have to fuss with them a little to get it set up right.

I don't want to reinvent the wheel here, or assume you have not done this but its pretty easy.  Just bring the engine to TDC, #1 on the compression stroke, ZERO on the timing mark, install the distributor so that the pointer on the rotor is EXACTLY at the #1 terminal on the cap.  That should be enough to get you started. 

Where are you located?

We're going to get at it again today. Thanks for that info, we're going to try it and see what happens. I'll keep you posted

I was thinking if you were nearby, I would try to get to you.  That would be fun to watch and bring me back.

It's really trying to start, trying to get it over that hump 

Recheck the firing order

Check for spark

Check plug gap, I believe .035 (wow out of the cob webs)

Check that the coil is powered correctly

Did you check that the timing chain marks on the cam gear lined up?

Fuel pressure, (using OEM pump?)

Pull top of carb over check fuel level and that the float is free

Choke slightly open, not tight closed

Spray starting fluid in carb, does it start?

Hold foot to the floor, see if it starts

Check compression, add table spoon of oil to each cylinder if low. (I think you did this)

Never stand in front of engine when cranking (your hair will get singed off don't ask how I know that lol)

I miss those days. And yes you are right about not standing nearby. It happens quickly lol.

I second checking that firing order.

Curious.....I think Rockfangd asked earlier...... What exactly is this 'reman' engine? Was it in a crate or anything like that? Where did it come from? 

Does it look fresh? Has it ever been installed in a car? 

 

What was wrong with the original engine?

 

Thinking maybe timing chain marks off or wiped out cam lobes...
