When I did mine it didn't look bad, but I hit both sides with a little sand paper to make sure there was good contact. After that I had nice blue spark and the saw fired right up.
Good luck on yours.

Well, I did - but no pictures. I failed to find out how to transfer pictures from my current phone to the computer. It was easy with my older one, but I didn't think of it when getting a new phone - imo phones are for talking and short messages, nothing else.
I refuse to join the idiotic I-phone trend.
Never acknowledged 'dual' bars than ran .404 and 3/8". I mean it's rather pointless here in the PNW as it was always .404 bars in either .058 or more commonly, .063 gauge with skip tooth chisel. I started in old roller nose bars-General, then went to Oregon and finally to Cannon. I can appreciate different settings all over the world. But it wasn't common practice to take the big .404 pro chain and try to make it work on smaller .050 bars like Niko alluded to. I don't care what was hypothetically possible. And like I said, if anyone was ever doing that, show me at least a discussion about it and a reason they did that.
No doubt I even used 'dual purpose' bars without even knowing it. Like I said, there was no reason to do a 3/8” conversion like that. All my large J'red run .058 gauge bars. That was the correct bar gauge for those saws if you wanted to run .404 pro chisel. .063 was too much for those saws to handle. Back in the day(OK, everyone toast!), when the people at Baileys knew what they were talking about and selling, that's the bar gauge they sold you for .404 pro chisel on the 80/90.
So I guess the moral here is;I won't talk about past practices on a world scale if he won't talk about past practices in the PNW.

You got it now...just make sure the instant it's buried in wood it quits 4stroking and screams evenly. Are you close to 3/4 out on high(sure sounds like it...don't be tempted to turn in further than 3/4)? And as a FYI, never run a powerhead like that without a bar....bad juju. Do all that with the bar on it.

Take some plumber's sand cloth(not the kind with the holes) and drag it through the points one side at a time. There's an almost invisible coating of corrosion that forms in there(especially in saws that sit for long periods)...you need to make sure that's knocked out....don't trust your eyes. You must have corrosion issues in that balmy climate. We had them bad in MO. We're all tellin' ya to stay with this factory points system because it's nearly bullet proof once set-up right. I've been in my 80 point box three times in 35+yrs. One pull saw when warm....1-3 pulls even in the dead of winter when cold. My 90 is the same.
Kevin
Duh question really....what other semi-modern J'reds would have a flywheel/fan housing that HUGE? Lol.......now back in the day(toasts!).....

True but the fact that your .404 chain doesn't fit between the bar rails of your 3/8" bar just means that your bar has to be .050, and not .058.
Two rings are.....better for longevity and a lot of other reasons!
Kind of a rare duck they say. Little brother to the 70e, not a lot were sold in NA. There's a collector out there that is trying to have every J'reds from the XA onward....the 66e had eluded him for a very long time....finally found one.

Two rings usually means that it is a 66e top end, not a 70e one.
Thanks @SawTroll! I thought that's what you said but wasn't sure. My memory never was real good and it hasn't gotten any better. I also have to thank @Modifiedmark for the bar he supplied for it. Thanks Mark!

Well I will most definitely give this a try when I get back home, and I thought this saw had an electronic ignition and not points? Did I miss something because I don't understand some of the lingo on here, I'm still really new at this, only been at it a little over a month now.

That's debatable, ay least there are some +/- with it - but I'm not going there in this thread.
Some people leave out the lower ring on two ring pistons when having the top end apart - or replace the piston with a one ring one when it is an option.
I was just responding to a thread about J'reds and points...if the saw in question is a 70e, then yes, no points! What saw are you referring to? OK I remember, we were talking about where to get a factory module for your saw(70e), correct?
Kevin
Certainly is debatable and even subjective by experience....no - in two rings other than they rev slower then one ring pistons. But yeah, not going there with you.

Yes it is a 70e so should I still hit them with sand paper or plumbers cloth per @beavis331 suggestion?
Just that one brass connection that Robin discussed earlier...and putting the washer in between so that you're certain of contact. I think you said you did that and no joy? Also, pull that wire off that grounds to the OFF/ON switch....so you know it's not the switch or a bad wire. If the module is going to ground, you're not gonna get spark just the same as a bad module.

Well I did pull the wire off of the on/off switch and tried but nothing happened, but if the contacts are still dirty then it would have been for nothing. I will try running some of that plumbers cloth over it and then go back to square 1
NO! Lol...you have no contacts(points), electronic ignition.....did you try cleaning up that brass connection that Robin talks about? I'm pretty sure there was a pic & location to go with that.

That was the connection I was talking about that I looked at but I didn't really see anything that looked like corrosion on there, it's also the same connection I stuck a small washer in. And if I'm not mistaken it was silver looking, but I believe someone said they can be nickel plated?
