there should be a little screw to help adjust your idle try that..counterclockwise to add more idle, clockwise to slow idle..

Reduced engine power message


You don't say what make an model vehicle ! But with most vehicle makes it has to do with the Throttle Actuator Control (TAC) System , electronic throttle control ! are you having reduced engine power ? There are probably DTC'S - diagnostic trouble codes stored in the PCM - engine computer .
The throttle actuator control (TAC) system is used to improve emissions, fuel economy, and driveability. The TAC system eliminates the mechanical link between the accelerator pedal and the throttle plate. The TAC system eliminates the need for a cruise control module and idle air control motor. The following is a list of TAC system components:
?€¢
The accelerator pedal assembly includes the following components:


-
The accelerator pedal


-
The accelerator pedal position (APP) sensor 1


-
The APP sensor 2


?€¢
The throttle body assembly includes the following components:


-
The throttle position (TP) sensor 1


-
The TP sensor 2


-
The throttle actuator motor


-
The throttle plate


?€¢
The engine control module (ECM)


The ECM monitors the driver demand for acceleration with 2 APP sensors. The APP sensor 1 signal voltage range is from about 0.98-4.16 volts as the accelerator pedal is moved from the rest pedal position to the full pedal travel position. The APP sensor 2 range is from about 0.49-2.08 volts as the accelerator pedal is moved from the rest pedal position to the full pedal travel position. The ECM processes this information along with other sensor inputs to command the throttle plate to a certain position.
The throttle plate is controlled with a direct current motor called a throttle actuator control motor. The ECM can move this motor in the forward or reverse direction by controlling battery voltage and/or ground to 2 internal drivers. The throttle plate is held at a 7 percent rest position using a constant force return spring. This spring holds the throttle plate to the rest position when there is no current flowing to the actuator motor.
The ECM monitors the throttle plate angle with 2 TP sensors. The TP sensor 1 signal voltage range is from about 0.5-4.25 volts as the throttle plate is moved from 0 percent to wide open throttle (WOT). The TP sensor 2 voltage range is from about 4.45-0.7 volts as the throttle plate is moved from 0 percent to WOT.
The ECM performs diagnostics that monitor the voltage levels of both APP sensors, both TP sensors, and the throttle actuator control motor circuit. It also monitors the spring return rate of both return springs that are housed internal to the throttle body assembly. These diagnostics are performed at different times based on whether the engine is running, not running, or whether the ECM is currently in a throttle body relearn procedure.
Every ignition cycle, the ECM performs a quick throttle return spring test to make sure the throttle plate can return to the 7 percent rest position from the 0 percent position. This is to ensure that the throttle plate can be brought to the rest position in case of an actuator motor circuit failure. Observe, under cold conditions, the ECM commands the throttle plate to 7 percent with the ignition ON and the engine OFF to release any ice that may have formed on the throttle plate.

I took the throat plate off to clean my Imagine serger. When I try to put bak on it has to be pushed back down and is against a small piece, seems to be too close.


THROAT PLATES ARE HELD ON EACH SIDE WITH A SMALL PIECE OF METAL (SPRING). 1. PLACE THE PLATE AT AN ANGLE OF THE THROAT. 2. AT THE SAME TIME CAREFULLY PUSH EACH SPRING UNDER THE PLATE. 3. SLIDE THE PLATE TOWARDS THE AREA WHERE THE PLATE SHOULD FALL INTO THE LOWER POSITION.

Problem with Hamilton Beach Brewstation I have the water tank apart and I need to know how to put the spring and seal back in


I'll assume you have the pivoting arm with the rubber washer stopper apart. The rubber stopper pulls out of its housing. If you have that out you need to stuff it back in its hole with a small screwdriver. If not: the pivot for the arm rests in two grooves; the arm is held UP with a spring under the arm. (The top of the washer seals the dispensing hole from inside the pot.) The pot has an indentation the spring fits in, the arm also has a depression to hold the spring. It's tricky, but u can get everything lined up in order to put the holding plate (with the 2 screws) in place. (Hold the assembly in place with one finger and with the other hand put a finger thru the holding plate. Move the holding plate toward its final position and switch fingers holding the assembly in place. You're now holding the assembly with the finger that has the holding plate.) Position the holding plate and tighten the screws.

Trigger stuck on full


This machine has a metal throttle rod from the trigger to the carb, you need to look at the side of the carb where the rod connects to the carb, with your finger ( with the engine stopped ) work the carb throttle spindle manually to see if it is moving freely and it springs back to the small throttle idle screw easily, if it does unscrew the idle screw with a cross head screw driver until the machine idles ok, if not you need to take the l/h side cover off to investigate what has happened .

Seat Position Cant be moved


The manual lever to release the seat is supposed to have a spring on it to return the release lever to the lock position, if the lever does not spring back when you let go of the seat adjustment lever then you know there is a missing, dis-connected, or broken return spring.

If this is the case try putting the seat where you want it to be and make sure that the adjustment lever returns to the lock position, now check to see if the seat will lock in with the adjustment lever in the lock position.

If it does lock in repair or replace the return spring.

Make sure that the adjustment lever is attached to the locking linkage and it does move the locking mechanism.

If it still does not lock into place then there is something wrong with the seat locking mechanism, and some WD-40 sprayed onto the seat rails and track might release a stuck mechanism, and if everything seems to be working alright, and you can see that the locking mechanism in the seat rail is moving in and out of the lock position, then the locking tabs are most likely sheered off and you will need to replace the seat.

Also look under the drivers side seat and compare the lever position and the linkage connections with the passenger side seat, and make sure that it is all operating like the drivers side seat.

Throttle control won't work after i cleaned the carb and disconnected the governor. when i move the throttle handle it does move the throttle control on top of the carb to the high position but when i...


Hi again Ed,
Starting at the carb throttle shaft, your linkage rod (with tiny spring wrapped around it) should be connected directly to the governor's arm. If there's more than one hole in the arm, connect the rod in the upper-most hole.
Now, at the base of the governor's arm is another hole (possibly on a tab jutting from the arm). The main governor spring should be hooked in this hole and then back to the sliding throttle control that moves when the lever on the dash is moved. (This one definitely has a tab and hole.)

The choke cable end hooks directly on the choke shaft and it has intuitive movement. Verify that the choke butterfly closes and opens relative to the cable control on the tractor's dash.

To insure that we only do this procedure ONCE, and we get it right the first time, let's set the internal governor to base-line at this time.

With everything bolted back up, move the throttle control lever on the tractor's dash to full throttle. Then get a 3/8 wrench and a slotted screwdriver and locate the round governor shaft coming out of the engine block. The governor arm attaches to this with a clamping-bolt. You will notice that the round shaft is slotted for a screwdriver as well.
Loosen the clamping bolt slightly with your 3/8 wrench, insert your screwdriver and rotate the round shaft clockwise until it stops. (It has VERY little travel, so turn it both ways to verify that your are at FULL clockwise position.)
Hold screwdriver there and move the governor's arm in the same (clockwise) direction until the carb's throttle is set to WIDE OPEN throttle. Still holding the screwdriver clockwise, retighten the clamping bolt with the wrench.
Next, move the throttle lever on the dash of the tractor to idle and back to full several times and observe the carb's throttle shaft, it should come down from full throttle to idle and back again freely.

Start the engine and be prepared to shut it off if it over-revs.
If it doesn't over-rev, your base-line settings are correct.

By bending the tab on the sliding throttle control (the one that has the main spring attached) you can now increase or decrease spring tension and change top speed of the engine. Do this in small increments and if you have a tachometer for single cylinder's set top speed to 3400-3600 RPM.

Sorry this is lengthy, but as mentioned above, we only want to do this once.

Hope this helps, and feel free to ask away if you need more info!

How do I get the rear ring clamp with the spring back on the front door seal. I took it of ok and have changed the seal but I cant seem to get the spring to strentch enough Thanks Mark LG wd 8013f front...


It takes another set of hands to stretch and hold the spring in place at the 3 and 9 o'clock positions. With the spring held in place in this manner, pull the remaining portion of the spring straight down at the 6 o'clock position with one hand and hold it while working the rest of the spring into the groove with the other hand. This is the toughest part of replacing these door seals, but it works better with two people. Please let me know if you need further assistance. I hope this helps you.
