Hello, I bought for ma MG TC a 123 distributor. I think the installation will be very easy.
But i don't understand which from the 16 possibilities from the special curve I should use.

I don't understand what I should do
I have a standard camshaft inside the engine

Good question. I feel like #2 would be the place to start. Unless I'm mistaken, that seems like the closest to stock.

Thank you for the quick answer, what is he difference between the different possibilities?

The main specification I'm looking at is where maximum advance occurs. If I recall correctly, max advance on a stock TC distributor occurs at 3500 RPM and 16 degrees. It looks like the 123 offers curves with a bit more advance, probably for modern fuel blends. Hopefully someone a bit more versed in advance curves will chime in.

the nearest is number 1, 3600/17

You're right, I didn't notice that the first one was zero. so I meant the second one on the list, which is actually number one.

Franz-
It it a standard GB-4-R from the 123 website, or did you have to special order?

It’s the standard GB 4 from the 123 website, comes with the gearwheel mounted for XPAG

Sorry my englisch is not perfect
