Daniel,

Me too...I've been reading and reading about:
  • Fuel line set up
  • Dead head fuel regulators
  • Fuel line sizing
  • Return line vs no return line
  • 90* angles in fuel lines
  • Fuel Pumps
  • Float settings for Holley
  • Heat shields
  • Fuel Pressure Regulator Mounting brackets
  • The list goes on...

Anyways, my Jeep is running but with my Fuel Pressure Regulator completely open. It will not run for a long period of time with the fuel pressure regulator adjusted to proper pressure. Venturies start to dribble after engine is warmed up for a bit and floods.

I'll figure this out later, and move onto my advance curve. I have some springs to mess with, but not sure they are stiff enough to what I currently have. I'll find out once I rip into my dizzy though...

I hope all is well with you Daniel. Also, I think your Mom's shop might be a blessing in disguise...Take her shop to a new level...customer service is huge!

All the best.

SC

That's great advice Steve! Thanks! I've been doing my best and its working out well, they've started to trust me with more major work. Like today I started and almost finished a rearend swap on newer mustang. Same axle as before, but the newer housing had upgraded axles, and a larger spline count pinion. Bummer is yolk on the new axle isn't compatible, but mustang parts are cheap. By almost finished i mean it needs a yolk, then I'll put the brakes on and the wheels and be done. Also did three oil changes all in 5 hours.

Just to be clear, does the starter turn the crank, but the engine doesn't fire? Or does the starter not turn, and all you get is a "click" when you try to start?

Pull a plug wire, stick an old plug in it, and set it near a ground. Then crank the engine. If you don't see a spark, it's most likely the ICM wiring.

Well...I'm still here. I have the fuel issue all sorted out and the jeep is running great! I've put 4 tanks of gas through the new set up and I'm getting around 12 MPG around town driving. Before I was getting around 8-11 but the 11 was a rare thing with 9 being a good average. So, I did pick up 3 MPG which is a good thing...

Mixture screws are set out at 1.25 turns with 16" of manifold vacuum. Seems that's the sweet spot...

Problem I'm having right now is that in decel my mufflers are popping and assume this is a manifold leak. This all started when I installed the thick gasket between the intake and carb. I need to correct this first and get back to the tune...

Sorry guys, but be patient...I'm getting there ...

So to pilot this thread for a while, my CJ refused to pass smog, and then failed again after me tuning it. So I've been kicking myself thinking my tune is apparently a golden turd, but i was pondering this evening why it would pass last year while running like crap, but won't pass this year running like a beast, and I think I may have realized it.

For information's sake, I failed because at idle I produce double the CO and double the hydrocarbons I should indicating I was too rich. So I put leaner main jets in it (because its hot now and the mains effect the idle slightly), then I vac tuned the idle screws. I dropped my hydrocarbons close to passing, but my CO went up!?

So I did some readings and it seems retarding your timing and retuning will lower your numbers. Then I realized since I run on manifold vac, my timing at idle is very high! Correlation! So I think I will simply port my vacuum advance and try it again when I get the chance.

What do the pros say?

Yeppers. Drop the initial down a couple of degrees and get it back on ported vacuum advance. Once you pass, make it run like it should again


Shawn

Edit: Now that I think about it, that should've been mentioned. My bad

No worries man. A Lot of good info has been learned here in this thread, and now this will stick extra hard with me

If I pass tomorrow, I'll be stoked that I figured it out! If not, I'll try something new.

Daniel,

Great work! I would of totally forgot about the manifold vac advancing the timing at idle...fingers crossed and I can't wait to hear what happens tomorrow.

Hey, on another note...when you plot your centrifugal curve is it necessary to plug the end of the vacuum line that is attached to the distributor or does it matter?

Thanks Steve! I think I'll postpone the test until the weekend. I'd have to leave the jeep in an unattended, unsurveillanced parking garage in downtown loonyville for 12 hrs while I'm at work in hopes of making it to the smog place by 7 PM. I got to thinking about how sketchy that was, an then I backed out. But Saturday is the day!

Also, it shouldn't matter if you don't plug the dizzy end of the vac line. There's no way anything can draw enough vac through that line to change the timing. And it's likely you wouldn't get contaminants in the few moments it would be disconnected.

Thanks Daniel.

I figured, but just wanted to make sure I was not missing something...

Good luck!

Steve, if you disconnect the vac line at the dizzy, while keeping it hooked up to a vac source, then yes you will need to plug the line.

If you disconnect the vac advance line at the source, then you need to cap the source.

Clear as mud?

Got it!

Still need to plot my curve one more time...just to make sure I'm reading what I'm reading...
