What happens when it kicks back at the bottom of the stroke?
Your knee hyper-extends, the kneecap swells up like a cantalope, and you have trouble walking for a few years.

Been kicking fixed mags for a few decades now, not really a big deal.

My point is that success comes from good technique, not luck. As long as your knee is still slightly bent throughout the stroke, and the calf muscle is stiff, you may get a shock to your foot but no actual damage.

Or you could buy a 29600-62 plate.

I won't debate whether you should do this or not, but I'll say that the very early sportsters came with fixed mags. I believe the first year for the manual retard/advance was 1965, and they do wobble a little.

Should I not be concerned about the wobble on a manual advance mag that just isn't hooked up to anything? I wasn't sure if the movement while riding was enough to make things get weird timing wise or not. If it's nothing to be concerned about then I can stop where I am, I was only hoping to get it setup as more of a fixed config to eliminate the side to side play that it currently has while mounted.

Now I'm not sure we're talking about the same thing when we say wobble. Are you saying your mag is slightly rotating back and forth like from full advance to a little retarded and back again?
If so, that's not good and I can see why you would want to lock it down.

When I said the moveable mags wobble I was talking about the very small shake you'd feel if you pushed and pulled the mag base with your hand. To put a shaft into a hole and have it loose enough to turn there has to be SOME loosness though it's a very small amount. With a cable attached it should stay where the hand grip puts it.

Not sure what your situation is.

It seems like due to the mag being mounted on the manual advance/retard base without any means of controlling a "max" advance setting (using a spring or cable to prevent mag body from going past a certain point out from the engine, counter clock wise) there is slight back and forth play on the mag, in that I mean being able to "wobble" the mag slightly clockwise and also slightly counter clock wise from where it sits, we are talking maybe a 1/8-1/4 inch iof play in either diredtion. I attempted to tack weld the manual advance/retard base pieces into more of a fixed mag base to prevent this play from being able to happen but it still seems to want to wobble a bit.


Unsure if this is something to be concerned about, something that I can solve with a spring mounted somewhere to prevent the mag from rotating out past a certain point from the motor, or something that I should swap over to the fixed mag base so that it can't move at all and call it done.

Jeez I love this solution, went outside to check mine out and I don't have the same set screws in my base. Is it possible whoever put this together has the base piece the wrong way, so that the set screw holes are on the cylinder side and not accessible, rather than facing out? Here are a few photos - https://imgur.com/a/av3fTFd
