Mostly because the early starters suck in comparison. You can get a late model style starter on Amazon for around $60 delivered. And they are well worth it. I don't waste my time with the old style starters at all. If it ever gives me an issue, in the recycling it goes to be replaced with one of the permanent magnet gear reduction late style starters.

You can get either early starters or new gear reduction starters that fit either flywheel tooth count. And you can get either size flywheel for both motors. Just make sure you know what you have and order your parts.
