Boy if it ain't always SOMETHING!!

'bout a month ago I put a new set of points in the mallory dizzy in the '69. Now it'd been like 8 yrs since I put points in this truck, but with the limited use it did not have alot of miles on them. I did a full tune up with cap/rotor/points to just remove any chance of old age rearing its head.
After setting everything up to snuff, I made my way down the road a couple miles to the Sunday Arby's cruise. It just about did not make it to a parking spot . It started barely running, on like 4 cylinders. I did not stay long due to evening coming and wanted to get home before dark. I could not get it out of the parking lot. It would not hardly even run....then POOF it clears out and runs like always . It made it home without incident.

Now, fast forward to today. I start with checking dwell, timing, carbs, etc. Nothing out of place, but still won't rev hardly at all. Cough, backfire, chugg'n. After going thru things 5 times over, it dawned on me. I have a Mallory adj rev limiter, after disconnecting it....VIOLA' it runs PERFECT . Seems that the rev limiter was on it's last leg and now was cutting ignition .

With all the tearing dizzy apart, I went ahead and pulled one of the advance springs off(leaving only one lightweight one). After getting it all back to roadworthyness I made a pass up the big road...... . Wow, what a difference. It takes 2 gears to get it to start moving forward/straight. Really helped out big time(removing spring). It lets the timing come in right off idle(total at 40 degrees right now). I had done this to the 428 in race car a couple weeks ago. It did the same thing. Overall power has not changed, but just low end has drastically improved.


So, the moral to the story............... next time you have rough running issues...............unplug that freak'n rev limiter!

If it's not snowin' this week, I guess I'll have to take it to work one more time

 

Cool!

I've never been a big believer in rev limiters. As long as you have a big tach and watch it, you'll usually be alright.

 

Well, being a stick shift I like to have it. Not that I miss gears, but it keeps the rpms from hitting the ozone when you shift. It is not really a major issue but just a safety factor. I might shell out the cash this winter for a 6AL since I still run all stock ignition.

I run a MSD 6AL on race car and have high side set at 6800. It too is just a safety factor since it's a stick shift also. If I ran an automatic then there would be no sense in it.

Yup, I drove it to work today. One of the few nice days showing on weather this week. Sure is fun to drive....just a real pain in the wallet to fuel it
