Good info thx. I was turning it up on the distributor. If I sit it at 8 on the crank will the rotor be slightly off #1 and the tooth on the shaft not center in the pickup?

Are you absolutley certain that you torqued the intake correctly. Sbf intakes will give you fits if you don't torque them exactly right.

[acehogg69]

Yes I did and checked after I got it hot.

[acehogg69]

I just pulled the plugs. Set it on 8 deg BTC rotor is dead on #1 with the gear on the distributor centered on the pickup. Letta ya know soon. I also reset the idle screws to 2.wy turns.

[acehogg69]

Just my luck snapped a couple plugs off.....lol try again! I set it at 8 BTC on the crank with the rotor dead on #1 it should run right? Well no change. I am 96% sure I have the compression stroke up on #1. Got the rotor set right on it and it's backfiring through the carb. Should I turn the distributor CC or Clockwise??? I am truely at the end of my rope. Also the plugs 1-4 were soaked with fuel and maybe 2 off the left bank weren't wet,

[acehogg69]

Well I reset the distributor again set it to 8 on the crank kept trying to get it running, no go, I took it out to around 16-18 BTC got it running. Then backed the idle screws out, wayyyyy out. It's iding and will run but stumbles and shakes on accel. Timing still outta wack? No more backfiring. Any ideas why this thing runs at such a high timing advance? The timing chain off?? Just pulling stuff outta my rear here. Also I read that the a/f ration should be reading around 13 or so at idle I could only get mine upto 7-8. Any ideas

[acehogg69]

I got from another website set it up for 10 Deg BTC which I did. I will post the info from there. Very helpfull! Question I have now, do I disco the wireharness off the distributor when I set the timimg? I know I need to disco the vac advance and plug it..

[lmsport]

Are you positive about the firing order/camshaft?

[acehogg69]

Yep tried the 1,3 7 not HO engine

Check for a vacuum leak, a big one, like carb base gasket not sealing.

[acehogg69]

1. Could I get clarifcation on the accel pump linkage setting. 2. Got it set 10 deg BTC. Which I know she won't run, which way do I need to move the distribuator, I need her at 16ish 18 then with any luck I can look for vac leaks and then start working on carb issues.

Accelerator pump link on a 1405/1406 goes in the center hole.

Super simple carb for the average guy ---
7/16 float level, 15/16 float drop. Follow the IB for the proper jets, rods and springs. You do have to read it a couple times for it to make sense. This is the first of 2 1405's (one with the choke option) I rebuilt last week - the other and still cruddy(!!) is behind it:



Timing should be no more then 10* BTDC

Ford OEM distributors only run on ported vacuum - pass side port on a 1405/6. Cap the other small one off or if you have a C4, run that line to the transmission

The front big vacuum port is for the PCV, rear for power brakes.

This photo shows #1, and the distributor rotates CCW as you look down on it (this is an HO wired dist, but #1 stays in the same place either way)



Get a vacuum gauge on that engine. If it has a stock camshaft, it will run 17-21 inches (mine is 17-18 with a medium warm camshaft)

Unless you understand pedestal mount rocker arms, don't disassemble until you do - they can and WILL cause you to suffer acid reflux

IRELAND THX FOR THE INPUT!

This thing won't do anything under 18ish. I am suspecting a vac leak. I put a gauge on it and with about 5-7 turns on the idle air screws,she it fluxxed between 7-8. She is idling and under no load not bad at all, how do I begin to chase done a vac leak? Under load,surges and is afu!
Where I do hook up a vacc gauge do I hook it up to the pax side or drivers side. I am shooting from the hip here, with the timing being so high maybe a other than stock cam coupled with a vac leak or would the leak cause me to over compensate on the ign timing?

[acehogg69]

Ireland, Happy belated b-day mine hit on the 10th.

[acehogg69]

to post more info, it is a stock duraspark iggy and distributor, all new
