Well, it's not just Ramblers! Any car will run like crap until it's got the right parts. The coil is easy to miss. GM used internal resistor coils for the most part, Ford and Chrysler an external ballast resistor. AMC used either Ford or GM based electrics, depending on year/model/engine. Just keep them all the same and you're good! 

I know there are a few exceptions, like the Prestolite electronic ignition used in the late 70s, and there are exceptions with the GM/Ford internal/external resistors, but in general... just watch out for the exceptions!

Unless you're just fascinated by points I'd replace those buggers with a Pertronix unit. No more burned points, more consistent fire, and you can run a hotter coil and a little more plug gap. Plugs will last longer and you'll get 1-2 mpg better on average. You'll also have more consistent power as the electronic unit doesn't wear/burn over time and have to be tuned every few months (depending on how much you drive it). You won't get more power than you will with fresh points just set correctly, but 2500 miles later you'll still have that power, whereas with points you may lose 5-15 hp (depends on how much they wear). Not real noticeable since the loss is gradual, but that extra mpg will help in the long run, and that little extra power might...

tonight i have success, after replacing just about everthang..on the motor ..it looks like the culprit was the wrong coil fitted , a coil with a built in restitor was fitted and "wammo" perfect idling car , that now can do 70mph in second gear with out to much problems ......the motor purrrrrsss , is resonsponsive , and is quite  i really cannot believe it , its almost like i changed the motor.....all because of a wrong coil......jezzzz it was really frustrating  at times  but thanks to everyone that helped me with clues/ideas wot to look for  the rambler is all sorted and on the up side of things everything on the motor has been replaced so the car should give me now truble free cruizin!

bloody coils

Make sure your coil wire polarity is correct...even if thats wrong,  that still shouldnt burn up points that fast.  It sounds like a combination of chines points and no resistor wire. I havent put in points yet that were chinese, but my god, i know the quality has gone down on the point set i last bought 8 years ago and they probabably wer still american.  It sounds like a  straight 12-14.7 volts is going to points when in running mode.   To check, you could prevent starter from turning by taking big wire off starter, connect  VOM to coil and activate ign switch and look for   the full 12 v during full key stroke, then less volts at run mode.  Fix that bloody thing...hey, how much for 89 octane down under?]]> Thu, 03 May 2012 11:28:08 +0000 http://theamcforum.com/forum/engine-mystery_topic37624_post358115.html#358115 http://theamcforum.com/forum/engine-mystery_topic37624_post358081.html#358081 Author: aussie rambler

NEWS FLASH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
POSTIVE NEWS!!!!!!!  ..........................................................  F/ME..... there is a god

OK , so tonight the car is running like a dog once it warms up , and now the lifhters are rattle so so bad.....now this sounds crazy ....but ....after i just got the car i changed as per usual , plugs ,oil/filter, points , car ran great then go worse, the alternator died ..i replaced it , but the car started to run like a ol junk yard dog.....only once it warmed up , backfiring etc....if i turned the car off when hot ,it would start up straight away , run perfect for a couple of minitues the splutter and backfire....so this is wot i did
check for vacumn leaks  on manifold titghted it /tested /tightend again
checked /pulled off carby ,changed base gasket as was a bit dodgey ....
checked vacumn wipers
replaced petrol pump- filter
replaced dizzy cap /leads/coil /capositor
replaced  /removed smog pump set up , installed new air cleaner set up
BUT  car still runs like a pig .........so
i then removed cleaned rocker gear as seemed to have bugger all oil supply , thus maybe lifters not workin properly???, ..........car is now running bad only when warm........check cam lift etc , valve gear still noisey and car backfiring /poping .........burnt valve?????,,last resort...,off with the head i think ..............as per last post ..................

LATTER TONIGHT ,  my brother comes over and when go threw everything from step one .....gunna be a long night ....everything is looking normal as the car is still running bad bad bad ,.......we get to the dizzy new cap /leads etc and BUGGER ME  the points look like they have been NUKED!  like the plastic is melted! dead /finished /el caputto.....and they are only 1 week old !!!!!!!!!!!!!!!!!!, hello hello ,hello ......we threw in a new set of points , the car now runns PERFECT!!!
!

BUT WHY ARE THE POINTS MELTING?????  that is my question??? .....so we havent worked this out properly as our multi meter is at my brothers car yard ....a job for the next day ....Have you got a idea or wot to look for??? im thinkin something is weird as problems only started to happen after i changed the  orignial motorall a alternator .as it stopped chargin......mmmmmmmmmmmmmmmmmmmmmmmm

We now attack the noisey rocker gear , i t is not gettin enough oil .....plenty of oil pressure , i clean ed the rocker gear already and cleaned the oil gallery etc on the second rocker bolt at the back, i didnt do the head bolt as i dont have a lathe and was intending todo it at my mates place who has a lathe ......well off came the 3rd rear head bolt ,  and we thought  "well %#$^ it" straight on the bench grinder, and grinded a big chunk off the sides , ........cleaned the bolt , sprayed carby cleaner  down the bolt hole +oil passage ...used a bit of fence wire , more carby cleaner......threw the head bolt back on ...and stuff me mate , there is more "texas tea " coming out of the oil gallery than ol "jed clampets backyard".........no more rocker noise /gone .......unbelieveable ......im excited ...

Wow, you must e ready to run it off a bloody cliff.  Have you checked manifold bolts? or sprayed carb cleaner looking for vac leaks?]]> Thu, 03 May 2012 04:50:57 +0000 http://theamcforum.com/forum/engine-mystery_topic37624_post358052.html#358052
