RallyRoach

1984 4runner with 22r carb motor. Installed an MSD 6-AL and a new coil on my truck tonite. Now, I can't seem to get the idle settled down, very high. Otherwise, truck is running good, smoother and no more backfires. All vaccum lines are correct, carb was rebuilt less than 2000km ago.

I reset the idle mixture to the stock 3.5 turns out. Tried turning the idle speed screw all the way in too, no effect. Still idling very high. Best guess is 2500-3000 range, but no tach anymore because of the MSD. With the stock ignition, it was idling at 900-1000 comfortably.

Open to suggestions here, but I'm guessing I'm not adjusting something right. Be nice to get it sorted out for the run on Saturday.

You turn the idle screw on the carb out (counter clockwise) to lower the idle, also check your timing, if its advanced to far it will cause a high idle.

Thanks for the info, got it all fixed. The timing was waaaaay out. sticky throttle cable too. Running good now, so I'm hitting teh trails tomorow. I'l post some pix and a trail report if anyone is considering the swap.

No tach? You should be able to hook one up to the - post of the coil. Or if its designed after the stock coil, there should be a pre-arranged plug.
