1.5 ohm 6v coil eh?

i think you may have a bit much primary resistance. i'm countinh 4.2 ohms. and that will make for about 2.85 amps

and since they are a plain cermaic type. they will be like that when cold.. menaing it may start hard. using the oem ballast resistor with it's thermal properties is usually more desireable, as it is lower ressitance when cold. still. if it WAS running with that setup. no need to muck with it. front coils are all over the place these days. I have seen plenty of 6v front coils that are .8-1 ohm.

1.5ohm is almost in sidemount 6v coil territory.. :)

Yes I thought since another post thread here said to keep it around 3.5a or lower then it would be safe so I left it like that.... it was starting ok just not running for long or tach-ing up. if I took one of them out. (I'll check the OE one, it's still under the dash but looks pretty bad and the one on the 2N was broken in half so I can't use that one) will it be ok at 4.4a ?

if it will 'start' like it is.. don't mess with it. starting will be the hardest part.. once started.. it should run fine.

again. if good spark on a cold start. go with it.

Welp turned out to be the breaker plate in the distributor is bad. it had some rust on it and the screw where the spring on the bottom of the coil broke out of the breaker plate. It was pretty clean by then I guess the PO cleaned it somehow but what was left was just too weak.
So the new breaker plates come with the nose bushing so while I'm there should I get the shaft and weights too? the shaft seems ok but the weights are pretty dirty and don't spring back like they should.

see if they will clean up and move freely. no need to spend money if you don't have to. if they turn out to be bad. of course replace them.. etc.
