Truck is running like crap ..sputter put ...points suck!

 

try getting new points and make sure to use a point coil and use the ballast resisitor. if anything is out of spec it will cause arching of the points.

 

a conder bad ot not grounded will cause issuses or a worn dizzy bushing. meaning the dist shaft bounces side to side cause point to open/close prematurely

Both EI distributors need a specially matched coil to take advantage of the higher output voltage. If you don't change the coil you will have to keep and run the ballast resister with your old coil and basically all you get is a breakerless (pointless) ignition system.

 

 

For $5 you can put new points in and problem solved. If the problem is a bad cap and rotor or bad wires OR if it's a badly adjusted carb an EI distributor isn't going to help now is it???

well lets us know what your looking for and find a Matchbox with the whole distributor mount(pedastal) and get the coil when you have time later

 

I assume you have a dual point dizzy now

 

 

yes places sell the distributor but nothing else like thew mount and timming plate. They assume you have the correct one already. PS they were 2 types of matchboxes and they use the common L20 mount then one uncommon so best to line up and find the correct stuff first

Dizzy FAQ if you haven't seen it:

If you get a used matchbox dizzy check for side play in the shaft at the top bushing, There should be very little play side to side, I've seen some worn enough the star thingy on the shaft hits the fixed thingy on the top plate (yeah, I can't think of the proper names). I don't know what that does to the spark but maybe it isn't good.

Look through the wrecking yards. These all had the desirable Matchbox style EI dizzy.

 

'79 620 truck

'79 A10 (HL510)

'79 S10 (200sx)

'80 2wd or 4 wd 720 truck

 

Earlier '78s all used the Remote Igniter style EI and in California it was also used from about '76 or so for better emissions control on most cars and the 620 truck. If you find a Remote Igniter try to find the remote box, it's usually under the dash somewhere, but if not an HEI module from a GM distributor can be substituted.

 

You should be able to find a Nissan EI dizzy and coil (don't forget the coil) for $50- $100, maybe less. They fit, they work and they are Nissan made.
