I checked my timing curve in preparation of purchasing a decent HEI unit. A while back, I tuned my distributor and it looked like this.

image-1445949515.jpg

When I checked today, it was...

12* @ 700 RPM
28* @ 1400 RPM
28* @ 2000 RPM

YIKES!!!!

My only guess was the springs fatigued, so I tore it apart and replaced my light and medium spring with two new medium springs. Then I tried again...

12* @ 700 RPM
15* @ 1200 RPM
23* @ 1400 RPM
28* @ 2000 RPM
28* @ 2500 RPM

Not a whole lot better, and what's with the jump between 12 & 14*??? Turns out the counterweights had worn on each other at 1400 RPM (where I typically wheel at and spend a lot of time at). It wore such that the advance falls into the 29* range into the pocket it wore and stays there. If it were loose springs, it wouldn't have stayed the same between 1400 and 2000 RPM since the max is mid 30's. that's my hypothesis anyway.

I hope it didn't harm my jeep too much. U haven't seen a drop in oil pressure or heard any audible pinging, so here's to hope. I will purchase a new dizzy before I run her again.

Good info Daniel, I imagine anyone who takes there Jeep off road could have the same problem. I spend most time on trails between 700 and 1600 rpm.

Ought to check your timing then!!!

Honestly I'm pretty sure a legit distributor wouldn't have an issue. Mine is some cheap knock off brand. Time for a real one. Probably go with a nice MSD one to match my wires

Here's pictures of my distributor weights.

Notice the dark spots. Those are heavily wore surfaces

I went to summit and bought the most expensive HEI advance kit I could buy ($15 from accel). This will get me by until I can buy a decent distributor.

Thanks Dave!

Only thing I regret is painting the cord. I may see if I can't take the paint off of it some day.

The best part about living in the mountains is the incredible clear blue sky! Today is a little less clear.

Back to jeeps. So I've been through 2 new weight sets (accel and MSD). Both promise to be stock style, and I haven't been ale to get more than 27 total with 12 initial. Both weight sets have shot the advance up dramatically like the stock weights. Weird. Something is amiss.

Pics again

I've never been able to just stare at the sun like today. It's just a full orange ball in the sky. The keypad has ash in it. Which is why it's in the pics.

Well I was able to get some janky crappy curve for now until I can afford a decent distributor. The curve is way too safe and I'm sure the jeep will be sluggish, but at least it won't be grinding up the bottom end. It hits 27* at 2500 rpm from 12* at 1500 and doesn't go any higher. Le sigh.

Perhaps I'll begin seriously considering GM TBI swaps since I'm looking at a qjet too which means even mo money
