No, I don't have a testing pump but I think I'll pick one up today while I'm out and about. I guess I just got eager to switch out the points.



As Chris pointed out, the problem was always there and I had originally assumed it was an accelerator pump problem. I installed a new carb and that helped all kinds of things but the killing of the motor when stepping on the gas hard from a complete stop is still there. This problem occurs on flat ground. Could still be a fuel issue but so far, it doesn't seem like it. Just trying to address one thing at a time so that I know what fixes it :)

Switching the points wouldn't be a bad idea anyways. I agree it sounds just like an accelerator pump, but the new carb rules that out. You could install an inline adjustable fuel pressure regulator too just for diag purposes and see if it is a fuel pressure issue or not. Seems unlikely though on a carbureted engine.

The previous owner installed an inline adjustable fuel pressure regulator along with an electric pump. The regulator is really old looking with a dial on it to set the pressure and I haven't verified if it actually works. Seems like no matter what I set it at, nothing seems to change.

I've had one of those before, they're pieces of shit. I had the same issue, I don't think it adjusted the pressure at all. Mine looked like this, I scrapped it when I realized it changed nothing:

:cheesy: OMG, that's EXACTLY what I have!! Okay, maybe I am having a fuel pressure issue. You mind if I ask what regulator you decided to use in its place?

I actually scrapped the whole thing. I had a little 1.8L turbo Subaru engine and I custom built the intake to fit a big ass 4 barrel Holly 670. This was a sandrail project. I was getting way too much fuel (you think?). The regulator did nothing, as you've found as well, so what I ended up doing was scrapping it completely and talking to a hot rod buddy. He went through the entire carb and used smaller jets and then we messed with the timing. Didn't even need the regulator. It ran perfect for the short time that I had it.

However, I have seen plenty that have a gauge right on them. I used one on 5.0 Mustang and loved it (fuel injection though). You can literally adjust the regulator and watch your fuel pressure change on the gauge so you know it works. I know I've seen them through Summit and other places, you can get reasonably priced ones. This is a similar one to mine on my Mustang:

Okay, been doing research this morning and apparently, the Pertronix 1162 that I got was definitely wrong and what I should have gotten was a 1165 which is made for a Delco 1110376 distributor.

While I'm at it, I think I might pick up the following Holley fuel pressure regulator being that it can be set to 1-4 psi. According to the FSM, I need to be running at 2.5 minimum with a fuel return (which I have).

:shock: whoa! Okay, I think that might be a bit more than what I'm needing but I do appreciate the heads up.

Nice. Good deal on both. Glad you found right distributor part. And as far as the regulator, can't go wrong with Holley.
 
Okay, spent the better part of the day installing a new Pertronix electronic ignition, a new Flamethrower coil, a new rotor and new distributor cap and... nothing! Engine cranks but won't come to life. Checked all the wiring - twice and still nothing. Tried bypassing the coil as a part of troubleshooting and still nothing. Kind of a bummer.

Is it getting spark? Maybe #1 changed on your distributor.

Are you getting spark from the rotor to the cap? If not, make sure points in new distributor are set right. Did you install it the way it came out or start from scratch with #1 TDC?

That's my thought, easy to change it and not realize. My new one only went in one way, it in turn made #1 at TDC where my old #3 was..

Hmmm, tried to install it the way it came out but now you got me thinking. May have to treat this as a scratch install. Thanks.
 
Just thinking about it, even if dist teeth aren't lined up right, spark should still be present. Even if spark is occurring at the wrong time, it still should be present. So if there is no spark at all especially from the rotor, it has to be within the distributor. I assume the rotor is spinning while the engine is cranked?

EDIT: Disregard this. I've been used to EI systems way too long and I'm on my 4th beer. Totally forgot about external coils, lol. If indeed dist is indeed in correct position, make sure primary circuit is allowing proper power and ground to coil.

Interested to see how this goes. I just bought this for my CJ7 and going to put it in this week. Mine came with no points so hopefully it works.

Good Luck

And #1 compression stroke, not exhaust, lol. I hope you get this thing figured out. Still fun to work on I'm sure. Keep us posted.
