Yes don't let it rattle even a little bit ... danger.

Some factory a-series engines have a retard module on them, at least here in the US (for emissions reasons). It doesn't just stop the distributor advance, it actually retards it (pulls it back). I wonder if these have enough range for boosted engines?

A mate of mine reckoned that you can get a double sided diaphram with two nipples. One going to a source of venturi vacuum, and the other going to a supply of manifold boost. that way on boost (all the time with my set up) the timing is retarded to take the load off the pistons when the charge is really getting crammed in.
I think 1200RC has something like this, but I'm waiting for a reply to my PM.

It's like torture, not being able to screw my engine right out to the redline. (without hearing that blood curdling ratle) It's like being impotent at an orgy.(of supermodels)

it's just a small mod made to the advance side of the dizzy. it's not a module. it holds the plate back in the dizzy and slows it's rotation therefore holding it back from advancing back to your static timing mark. this is why the simple fix of locking the timing is okay, but still isn't the best.

if you lock the timing, you get, say, 0

My forcefed a14 is suffering from bad detonation. Does anyone know anything about "Boost retard" modules for dizzys? I have been told to weld up the mechanical advance weights, but I was maybe thinking of trying to get some stronger springs instead.

I took her out today, and it was worse than usual. (Louder) And now it is rattling it's nuts off, without even giving it a real big smack of throttle.
Could be crappy fuel, it's been sitting for a week, and our pump gas stale faster than bread left on the dashboard on a hot day. (well not quite, but you get the idea.)
