You can adjust the idle on your Polaris 90 by turning the adjustment screw on the side of the fuel pump. Turn the adjustment screw to the left to increase the idle speed.
80/90 weight is the usual recommendation. If it's a posi, don't forget the posi additive.
On a 90-93 Honda Accord you can adjust the idle with a screwdriver. On the throttle body there is a screw on the top left above the intake duct. Just adjust until idle is in correct range (usually around 700)
The idle adjustment screw is on the back of the motor on the driverside. stand on the driverside up by the brake master cylinder look under the vacuum hose that runs on the back of the intake. the idle air screw is there under the hose. good luck!
check for broken or slipped timing belt...also fuel filter and fuel pump Also check the orange wire connected to the positive battery terminal. If it doesn't have a good connection the engine will turn over but will not start. Had the same problem with my '90 lemans.
On my '90 lemans, you have to remove two large headed black flathead screws on the panel below the steering column. That whole panel is hindged at the bottom and will flip down exposing the fuse box. Hope that helps.
i have a 90 lumina 3.1 i was told you cant adjust the idle, but i fyoure hvaing idle problems like i was try replacing the idle air control motor. Try cleaning it and the throttle plate. Go to bgfindashop.com and find a local repair shop that uses BG Products. The air induction cleaning will normally take care of those problems.
Check idle adjustment (rpm) then check timing, then check for misfire-start there.
You don't, there is no adjustment.
You should here the pump run for a few seconds if you just turn on the key then iT will stop. Then the pump will fire up again when you start it. ON A 1992 THE RELAY WILL ACTIVATE THE PUMP FOR 1.5 TO 2 SECOND IN THE RUN POSITION WITH THE CAR NOT RUNNING.
I just adjusted mine on a '90 750, and it is located on the right side near the rear carburetor. You can find a download for the service manual if you have an Acrobat PDF reader, then search for "idle adjust." There should be a diagram available there. If it is like mine that I found, it is diagram 120. Hope that helps.
'90 Honda Accord will start but shut off. What could this problem be?
