Starlet 4K Vaccum Advance Questions. Helppp :)

[CorollaNut68]

I'm not sure about yours..I just did this on mine...it's a 3K with the most ancient dual horn distributor with two vacuum ports, one for each horn. I have 3 available outlets, two from the plate under the carb and one from the carb itself. Normally I use the rear plate outlet to the rear horn and the one from the carb to the front horn..give it gas, it sucks in and advances the timing. (after returning the engine to all stock except for a .20 bore it was pretty sluggish even timed perfectly), but when I put the front horn on the front plate outlet it sucks in all the time keeping it advanced. I unscrewed the idle adjustment all the way and it won't idle hardly below 1200 or so, but it starts better and easier, it runs better down the road. I may try putting it back and just twisting the dizzy a little forward of normal, just shy of clatter and see what happens then......of course the gas is getting crappier and crappier around here...this thing was born to burn rice, not corn!

Good point, and this will be an ongoing problem as Govts push more and more alcohol into our petrol. Our cars will get fewer on the road and they won't care whether we can drive them or not, so we will be modifying constantly to keep up with fuel changes.
