123 ignition on euro 07/73 tii

[IanIreland]

Hey, I have read so much amazing info on upgrading the dizzy on the forum. Question: sites selling the 123ignition distributor state that they are for cars WITH vacuum advance. Am I right in saying tii are MECHANICAL and VACUUM advance?

 

About to invest in one so need to get it right.

 

Thanks,

 

Ian

71-73 are mechanical advance only, 74 are mechanical advance and vacuum retard. Doesn't matter what it was originally, you can use the 123 either with or without vacuum advance. It can be turned on or off, or you could simply not plug in a vacuum source. 

 

I have both used and not used the vacuum advance on my 74, and she runs beautifully either way. Starts a lot faster too.

Ian,

The 123ignition product has a 'vacuum advance' feature...so its suitable for cars which require vacuum advance ignition system. A euro tii uses only a simple mechanical (centrifugal) advance, virtually all cars use this and the 123ignition supports this as well.

 

So, you can purchase the 123ignition & simply not use the vacuum advance feature, all will be OK.

I (briefly) used a 123ignition on my euro-spec tii and results were very good.
