Hey, all. I posted this in my introduction thread, but I feel here is more appropriate. I will post pics of the car later.
Iíve been enjoying this car as a mostly daily driver these last few years. Got some major body work done, etc.
These past few months, Ive been struggling with an untamable high idle. The newer SUís are rebuilt. Some details about the car:
-engine was rebuilt several years back by a reputable source. Under load at high speeds, she ran excellently.
-carbs are rebuilt. If I put on the old, tired ones, I still get the same result. Iíve replaced every hose I can, PCV valve, I even sprayed carb cleaner all over the place and can never find an air like.
-if I disconnect the hose from the PCV valve to the nipple at manifold, and plug nipple,there is no change.
-idle screws turned all the way out, still no change.
-Pertronix electronic ignition less than a year old, was working fine as far as I know.
-new Beru Blue coil, 12v 3 Ohm(I plan on getting the Bosch later)
-iPD plug leads all just a few ,on this old
-cap and rotor look good, theyíre newer.
-brand new spark plugs gapped at .028
-valves all at .020
-idle timing is at 10 degrees, I did the static timing thing. Drive pinion is all correct.
-distributor with centrifugal advance seems to be working fine. Springs are intact and functional.
-battery, alternator etc all good.
-carb pistons move the same, give a nice clunk when let drop.
-throttles open and close all the way. Dashpot fluid etc good. Linkage seems to be okay.
-if I pop open the float bowls after running it, they at the level they should be at.
-choke is completely disconnected and disengaged.
-I recently redid the head gasket. Lifters were all healthy as far as I know. All valves opened and closed as they should. Cleaned and replaced gasket with correct torques, etc, valve adjustment after.
When trying to tune the carbs, the rear carb seems to pull in way more air than the front carb for what ever reason. If I pull the plugs, that side of the engine shows me itís running super lean. Those plugs are whiter and dry, front 2 a nice brown.
And so, Iím finally returning to the forums for some help. Iím at a complete loss, here.
Anyone here might have any idea as to what Im missing here? Iíve noticed the idle drops a bit when under load, but only because itís under load.
I can drive it but it lacks any gusto. I plan on doing a compression test later in the week.
