It may seem simple for you all but I am not a mechanic. I have explained this to Steve.and Hainz. I don't have a timing light I am struggling to statuc time it. As steve has shown me...I enjoy the custom aspect and the style of the 620s. But unfortunately I really have nit learned to work on them. I have had friends and shops do the work over the years.  So if I can't get this figured out. More than likely it will need to go to a shop. You all are mechanics and the 5he how toos and enjoy it...I do not

That being said,, the coil had no ballist resistor .. if I need to put one on how is that done. And I don't know how to adjust the pertronix distributor plate 

If you have the right coil, you don't need a ballast resistor. Buy a Pertronix coil and be done with that.

 

There comes a point where things simply need to be checked and verified. Guessing can and will cause damage. Ignition timing is one of those things. If you set it by ear, it could be off and cause broken piston rings or even cracked pistons.

If you put the pertronix in the distributor with out pulling it out of the truck that means nothing really changed just turn the dist left or right and it should be close to starting and runing

 

I ASSUME this is the same distributor that was in there. But most L20 point dist hav that RING BOSS above the point Lobes where the Pertronix magnet ring wont fit over it. You got to be more precise on what you did and maybe photos.

So I was thinking about the issue I'm having with getting my truck started with the pertronix. And I decided that I was going to put the original distributor back in. Since I had swapped it out with a distributor that had the pertronics already in it from another truck. So I pulled out the distributor that was in the truck right now. And then I realized that the two Distributors are different. So I pulled the pertronics off of the one went to put it on the original distributor out of the truck. And I realized it would not fit onto the distributor. The part that the rotor goes on to is too big for the magnetic part of the pertronics to fit over. So I added some pictures the blue distributor is the original distributor that had the points that I've had on that truck for over 20 years. And of course the silver one is the one that came off the old engine off another truck and I just put it into my current 620 that we're having problems starting. So now I'm at a loss again.

22100-N8110 is not in my parts number data base. I have no idea what this was used on but not from N America L series.

 

As Hainz mentioned most L20B distributors are too large for the magnet to fit over.

[1lo620]

OK that being said...what the heck do I do if I can't get the magnet onto the distributor? And I am running a L18 it is not the stock engine

[datzenmike]

Get a single points distributor they have a smaller diameter spindle that the magnet fits.

 

I think you can dismantle the distributor shaft and have a machine shop trim it down to fit.

[1lo620]

I will give that a try this may be the issue..hopefully 

[banzai510(hainz)]

the  bottom photo the ring will fit on that but I dont see the 2 holes for the Pertronix to screw into . where the points screw down?

Kinda looks like  MITSHIBISHI DIST.

I have ran them before. I just wore them out then thrown away. Bushing wear

[banzai510(hainz)]

(1)You said you had spark with the Pertronix set up I believe. so it means it works.

so its got to be timing. to the right spot.

 

if the pretonix dont match the screw holes to go into then your done on that dist.

 

the top photo with the Pertronix installed. this will work but youll hsave to pull the dist shaft off and have that ring machine off.

I dont know why (1) would not have worked  if you said you had spark

[1lo620]

So I was thinking of just buying a new distributor. I see that they sell them on Ebay. Is 5his a good idea and if so is there a good place to get one.

Ok so I checked my Pertronix and I got spark. And I also got spark at spark plug #1

To me what you have works

[David Krouse]

Ok. I was going to take the bolt off to have it machined as you stated. So now how do I get it machined. That is why I was considering buying a new distributor..

[banzai510(hainz)]

well you said the other dist worked and had spark out to the plug correct? why not use that one?

So Im kinda confused. So it check out good why dont you use that distributor?
