    Car cover

    Yes, for long-term outdoor storage that would be the best solution. But it may not be practical for a daily or frequent driver. The biggest problem with car covers is once they get wet, you have to take them off the car, but then you have this huge, heavy, soggy thing to deal with. And even if...

    Car cover

    A $90 cover from Amazon isn't going to be custom-fitted to your car body. I strongly recommend a custom-fit cover. It won't flap so much in the wind (which beats up your paint), and will be lighter and more compact for storage.

    Car cover

    Yeah, there is no "best" cover for all circumstances. Outdoor in the weather, outdoor under a carport, indoor unheated, indoor heated — all those would take different cover solutions. Go to covercraft dot com or one of the other brands and read the recommendations. My cars are outdoors under a...

    It would be ******* great if I had a garage... Jesus, don't be so obnoxious. This is a temporary domicile until I can retire.

    I'm confused about distributor advance specs. Also, dual point tech.

    I wasn't messing around with idle timing at all — it was set to factory specs. I was just observing that I experienced part throttle pinging. I need to do more testing on that — I was just quoting speed from memory. It's hard for me to find a hill to test on — I live in the flats in a...

    I'm confused about distributor advance specs. Also, dual point tech.

    Well, I remembered that the vacuum advance unit I was running was a replacement that I had found on eBay, after the original diaphragm failed, and it occurred to me that maybe this replacement had a different washer pack than OEM. So I pulled out one of my spare original distributors for...

    Yes, that was pointed out already. But I read it here on FABO, so... That's why I was seeking confirmation.

    I can't run 87. I have to run 91 with the CR in the Commando (if I could get 93 I probably wouldn't have any problem). I think that fast curve would be worse in my case, and it wouldn't idle worth a bean at 0º.

    Hmmm. I happen to have an NOS (never used) CAP version of this same distributor (2642358, IBS 4013-B). I was wondering if it might be a good substitute. But then I looked at the specs. The vac advance curve is exactly the same. But the centrifugal curve is even steeper — it is + 24º to 28º @...

    Here is the curve diagram I made, as a JPEG image. Again, these are the factory specs, not field observations. Yes, you can see it is very steep initially. But I misstated the amount of timing — at 1800RPM, it is about 21 to 25º. So that's not as extreme. You can tell the table is not...

    No, remember, the table doesn't include the static timing. So it's 26 to 30º at 1800RPM, but it's all-in at that speed. Yeah, I know, fuel is the problem here. And that's what I was thinking — I need to limit the vacuum advance somewhat.

    FYI, here is the curve diagram I created, based on the spec sheet.

    I'm confused about distributor advance specs. Also, dual point tech.

    Thank you. Per the chart, centrifugal advance is all in at 3600rpm. The compression ratio on the Commando is nominally 10.5:1. I have TRW domed pistons which were supposed to maintain the stock CR, as opposed to the Egge replacement pistons which (I've heard) result in a lower CR. The...

    Thanks. In theory, it's maxed out at 12" of vacuum. I suppose, then, that substituting a lighter spring in the vac unit is what you do after you have removed all the washers, and still want MORE vac advance. Not that I want to do that.

    That's helpful. So, say the advance cuts in at 10" of vacuum (per the chart). Would adding an additional washer make it not cut in until a higher reading? Or would you remove a washer?
