Just get her drivable (2 Viewers)

There’s obviously some confusion about this that is causing some misunderstanding.

Not hard to do with me that's why I asked, thought I might learn something new.

I was referring to onemanarmy,

From what I've read, it needs to be pointed at the #4 cylinder when #1 is at TDC compression.

That in my world would be about 60° advanced and would create exactly what he describes,

It cranks and idles fine, just pings bad under load.

So here’s mine. This is a GM HEI. #1 position on the cap is in line with #3 cylinder. If I pointed the rotor at #4 cylinder, it would be in line with #4 position on the cap, which would only work if I were setting the timing to #4 cylinder at TDC.

 

[onemanarmy]

So this is what I was talking about. The distributor has only so much adjustment due to the tab that the hold down bolt goes through. From what I've read here on mud for timing a 2F is to install the distributor with tbr rotor pointing at #4 cylinder. That is what I did and #1 on the cap (cap is numbered) is in line with the rotor.

Is this correct? I have #1 cylinder at TDC compression before installing the distributor.

It cranks and idles pretty good, acclerates well, but under load in third and fourth gear I get lots of pinging.

I'm working on the timing again as I type this.

Could be air fuel mixture also causing ponging. If satisfied with timing try tweaking carb in small increments idle and fast idle.

 

[onemanarmy]

Figured it out...top pic is the way I had it, with pinging. Bottom pic is how it should be. Runs better now and no pinging. Got to have that #1 on the cap RIGHT ON the rotor position. Duh.

 

[onemanarmy]

Tightened up some loose manifold bolts and we have a smooth 2F now. Finally.

 

[RUSH55]

Sweet! Glad to hear

 

[onemanarmy]

So this part of the hood has been bothering me for years. So gonna do something about it.

 

[onemanarmy]

also, how do you remove the spring on the underside of the hood? I tried a variety of methods, but none seemed to work.

Thanks

 

[scrapdaddy]

I gave up and left it alone, didn't want to destroy the hood trying.

 

[RUSH55]

I tried as well for about 5 minutes and decided it was more trouble than it was worth to take it apart.

 

[scrapdaddy]

I used this product inside the cavity....Eastwood Internal Frame Anti-Rust Coating, 14 oz. Spray

 

[onemanarmy]

Well the pic I posted is the good side.

The underside is about gone and needs work. That pin/spring thing is really in the way. It has a slot in it like it would turn with a screwdriver, but I couldn't get mine to budge.

Yes, it will get a heavy dose of rust killer.

Reach through the spring with some vice grips and grab the unthreaded portion of the shaft, work it back and forth with lots of penetrating oil and try to get it to break free. Once you have everything dissembled the vice grips marks can be cleaned up with a file. Good chance you’ll need to weld a new nut on the back side anyway or run a tap through it at very least so I wouldn’t worry too much about saving that part if you need to use a cut off wheel to remove the assembly.

Good luck, I’ve had to remove three of them when I was prepping my hoods for my pigs.

 

[J Mack]

I’m assuming you loosened the spring retainer/jam nut already, if not just grab the outside with a set of channel locks or tap it with a hammer and punch before you try to remove the shaft.

 

[onemanarmy]

I have not...not done anything except look at it confused.

I'll take a stab at it...but if its gonna be a huge pain, I'll leave it.

 

[RUSH55]

Docu-drama. Spare us not one single step!

 

[RUSH55]

You have an FI unit on here you’re fine tuning? Don’t remember reading about that!

 

[onemanarmy]

Installed an Affordable Fuel Injection kit about a month ago.

Fined tuned (mainly timing issues) and appears to be all good now.

Have not taken it on a lengthy shake down road trip yet, but very soon.

 

[RUSH55]

Did you already post pics earlier in the thread?
Looking forward to hearing about how it works out.
