Dist advance?, where to hook up.... Options

[xsboost90]

ok, so the trans is back in and she is shifting much nicer now, but im noticing a slight hesitation along the acceleration. I remember the vac line for the dist is still connected to the charcoal canister temporarily. Now there are two vac lines on the dist, one closer to the base of the dist, im guessing this would RETARD the timing, the other on the outside of the diaphram, which would ADVANCE the timing correct? Factory says to put the hose on the retard line but this makes my car knock and ping like crazy! I have never really heard a clear answer weather to leave the VAC off, or where to run it to, how it works etc. I tried but cant find any clear info on this. I think i need a mallory dizzy...

All the info you need is available via a search of this site.

Anywho...

The one vacuum line you have on your TB on the 74 2.0 is for the retard on the dizzy. The 73 2.0 TB had both advance and retard ports, but they changed the TB in 74 to retard only (for emissions), but contimued to use the same dizzy. Hence, the two ports on the dizzy but only one on the TB for the 74 2.0. Generally speaking, and is the case with a 914, a vacuum port on the can of the dizzy is advance and the port on the 'back' side of the dizzy is retard.

You need to disconnect and plug the vacuum hose, time the motor, and then reconnect the vacuum hose from the TB to the retard port on the dizzy.
