With modified cars, all the modifications have to be taken into account. Everything matters. Perhaps the first thing you need to do is find out exactly which dist you actually have. Reasonable timing will be that which puts you at about 30 deg total adv at speed. Once you know what you have then you can find its advance curve and figure out what the setting should be at idle. If this dist has a vac adv can it is NOT a 009. I don't think the Webers have a vacuum adv port, and you don't want to connect the dist to intake manifold vacuum. Valves should be set at .004/.006 or .006/.006 (Intake/Exhaust) and are always important to keep adjusted. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Search old messages on the Web!
