Ok. Missing the choke stove. Got it. I will cap off the vacuum leak and try to convince him to hook up the electric choke.

Try 14 initial before recurving the distributor, or after?

Thanks for the help.
This is what happens when a ford guy tries to help a Chevy guy. 🙂

Do 14 initial, leave the recurve for later. Might not gain anything with a recurve.
I run 14 in all my stock motors at sea level. Higher initial at higher elevation.
Where in the world do you live?

Does he need to pass emissions tests?
That can effect your tuning.

We are in South Dakota. Roughly 1400-1500 feet above sea level.

No emissions to worry about here. No visuals or sniffers, and no vehicle inspections otherwise.

Will bump the initial and see what that does.

What do you think about lighter springs on the stock weights? Any benefit there?

For a stock motor not much to be gained.
Try 14.

It appears that someone who knew something has tinkered with it sometime in the past.

After a little back and forth trying to read the timing scale we found that it was set at 14 initial already. We advanced it a few degrees off the scale and it seemed happier, but they usually do. So in the end we set it back to 14 initial and hooked the vacuum advance up to full manifold and reset the curb idle back down to where it sounded happy.

I feel like a few more initial would be of benefit, but it is bordering on a grunt start when hot already. I’m not sure it would be happy on a hot start with 20 degrees in it so we might be near the limit already.

He is Going to drive it and see if there is any noticeable difference in anything. I’m not expecting much since we didn’t really change much.

Next up I’d like to pull the cap and rotor to get a look at the weights to make sure they aren’t fragged like mine were. I’m guessing they are fine because it runs well and the timing at idle was nice and steady.

I didn’t rev it with the timing light to see what the timing did. So we should try that as well to see if that tells us anything.

What could be done about a momentary bog when the secondaries kick in?

I was hoping that the increase in timing would overcome that tip in bog, but since he was already running it at 14, I doubt we cured it.

Is there any easy adjustments with the secondary damper?

I'd prolly just swap in some pistons and a mild cam ($350) for 350-375 HP and enjoy it...

Any idea where to get some secondary metering rods? That looks like a relatively easy and cheap thing to try.

I’ll share the idea with him. That’s a route I would go, but I’m not sure where he is at with it.

Did you adjust the secondaries air door to get rid of lean misfire off the line?

I won’t see him until Monday at the soonest. Exploring all ideas in the meantime.

My understanding of the problem is not so much off the line as punching it while cruising. I need to go for a ride with him and see what all it is doing. I didn’t have time to go for a ride on Friday.
