Hi! I have finally decided to buy a new distributor (123 ignition) for my 1966 Vitesse MkI 2-Litre (not modified in any way, twin strombergs and standard exhaust). I have searched on several Triumph forums about 123 ignition dizzys, and although I did find some interesting info I still have some questions. I have no problem regarding the lack of tachometer drive, I can use an electronic version. There are quite a lot of information on the forums about 123 dizzys, but not so much about how the engine actually performs with this dizzy (long time driving experience) and also which of the 16 settings to use. Especially feed-back from owners of 2-litre Triumph engines (Vitesse, GT6 or 2000 Saloons). Does anyone on this forum have a 2-litre 6 pot with a 123 dizzy? If so, how do you think it performs? Then there is also debate on the forums about whether to buy the fully programmable version or the “standard” 123 with 16 settings. I can understand the pros with the programmable version, but it is very expensive and I have a limited budget. Besides, I have this mental disorder (perfectionism) that comes and goes, and I’m afraid that if I had a dizzy with a million different possible settings, I would just continue to adjust the damn thing until I die trying to find THE Optimal Setting. If I only have 16 settings to play with, then there is at least a slight chance that I actually might finish the job some day… Some people mention the fact that none of the 16 settings match the original advance curve from the factory, and this is referred to as a problem. But how do we know that Triumph engineers fond the optimal and best setting? (They did make some weird designs, rear axel for instance…) Maybe one of the 16 settings in the 123 dizzys is actually better than the original? (Especially since the petrol are different nowadays). So, if anyone out there has a 2-litre engine with a 123 dizzy I would appreciate it if you could describe how it performs, and which of the 16 settings you use! Regards, Roger.
