I just post a question on BAT and figured I'd post it on here too, i know most of us do troll BAT on occasion
maybe some of the wise ones can chime in.
" Beautiful tii, as an owner of one, I can confirm the sheer joy of driving these cars.
Here is my confusion though, the car has a matching VIN engine, however, there are bits from a “typically” 1974 tii that came with a vacuum retarded distributor. That was for emission reasons. The vacuum hose running from the port on top of the manifold, between runners 1 and 2 (from the nose of the car) going to little bit on your air cleaner is give away… Oddly enough, in my one year search for my tii, have not seen that vacuum port on any pre-74 tii, in fact i never came across the vacuum retarded system on anything other than a 1974. Could it be because of late 73 production? or is the manifold and aluminum runners from a different car? Maybe some of the wiser 02er would know the answer. I’ll also post the question on the 2002FAQ and let you know if get any info. "
<Edit>... upon further review of the motor pics, it appear that you( or someone) as just hooked the vacuum lines to just go to "nowhere" ergo the distributor you have is not being vacuum retarded because if appear that there is no vacuum line running to it... your main line is running from b/w runner 1 and 2 to the vacuum control atop the air clearer to the thinner vacuum port (next too the tuna can/toward firewall) there should be a "T" there and one of the line runs to the distributor. With that said, some people, including myself abandon the Vac-retard dizzy for a standard Tii one, which most likely happen here, the odd thing is that those to ports on the manifold are just capped. Not sure why the system is still in place without serving any purpose... certainly not for aesthetic reasons.
