    Are you sure the carbs are clean and been synchro and tht the fuel level in the float chambers are at the correct level and tht the jets are not clogged especially the primary ones!

My 1981 maxim 650 idles high. what is the correct idle setting and how do i adjust


Hi, Robertshenk and the usual suspects are:
1. Throttle cables improperly adjusted or pinched.
2. Idle adjusting screw needs to be backed off.
3. Intake system air leak.
4. Fast idle choke ramp is not releasing.
5. Broken throttle return spring.
6. Damaged diaphragm or slide.
7. Faulty MAP, TPS, ATS, O2, VSS sensors or wiring/connector

My Ryobu RYO8554 only runs when it is in the carb lever is in the start position. ANy use of the throttle kills the engine. been that way since I bought it. Thanks Jim


Hi, if you have the lever in start that means the carb is choked. If you are only able to run the engine when the choke is on, then it is starving for fuel. First, make absolutely sure you have the right fuel mixture, then try to start the engine. If the mix is correct, then your carb is out of adjustment. Find the two screws that adjust the high and low idle on the carb. Turn the low idle one quarter turn counter clockwise and try to start the engine again. This adjustment will allow for more fuel to deliver into the cylinder. (adjust more if needed). The high idle may also be out of adjustment, so tune this screw with the throttle on high (and running) until you hear the transition between the high rumbling sound and the high even sound this point is you high idle. Good luck

Carb and throttle adj.


Here is how to do it. First disconnect the throttle cable to the carb and let it hang loose. Make sure the outdrive is in neutral and the boat is secured to the dock or on a trailer with a water ****.

Pull back on the throttle by hand directly on the carb throttle shaft. Observe the Choke cam on the opposite side of the Carb. Let go of the Carb throttle shaft and see where the Stepup Cam is set. The Choke plate should be closed most of the way. You will not have very much time to make an adjustment.

Start the engine and let the Choke work and observe the RPM. There are usually adjustments you can make to put the Stepup Cam on a lower step by bending the Link Rod if it is running too high in Choke. Sometimes the Cam is left alone and a screw similar to the Curb Idle screw on the Throttle side just needs reduction to ride lower on the Choke Cam.

After the Choke is warm, it disengages with a pull on the Throttle. Now you are using the Throttle side of the Carb to operate the engine RPM. You want a low RPM for sake of the outdrive gears and NO WAKE zone. The adjustment screw opens the Throttle shaft, You set it for the Manufacturers Spec. probably 550 RPM.

The Throttle cable is now adjusted so it pushes slightly against the Carb. This forces the throttle closed. The Throttle cable has threads and a sort of Knurled knob which runs on these threads. This device is used to lengthen or shorten the cable so that pressure is applied against the Throttle.

When the outdrive is in water you will has resistence on the Exhaust. This will slow the RPM. If the motor stalls you will need to adjust the motor to idle Specs while in the water.

For best economy, find a Vacuum port and attach a Vacuum guage to it and adjust the air mix to the highest Vacuum reading then turn in the Mixture screws slightly until the vacuum starts to drop.

Bike starts on choke and runs.Turn off choke engine will not tick over,any throttle and engine cuts out.any suggestions?


Very common problem, You will have to remove the carb.s and clean them. Gas dries and turns to varnish after 3-4 months, this dried gas clogs up the jets and ports in the carb.s. If you chose to do this your self there are adjustment screws on the bottom do not mess with these screws. Just clean the bowls and jets, clean one at the time so you do not mix up parts.

I have a craftmens 25 cc weedwacker thats about 3


it sounds like your carb is out of adjustment and you need to adjust it. Look at the carb on your weedwacker, there is an idle adjustment screw somewhere on it and using either phillips or strait screw head and then carefully turning it clockwise go 1/8 of a turn at a time until the engine idles smoothly.

Idles but stalls when throttled


If you have the TB2BP EC Troybilt backpack and it bogs down or begins to stall out at full throttle with choke in FULL OPEN try the following:
1. Do the simple stuff first, Check spark plug, air filter and clean or replace if necessary.
2. Remove air filter cover, open choke and spray out the carb with carb cleaner.
3. Inspect carb and look for a flat surfaced screw with a small V notch on the side of it. It will be on the top side just forward of where the fuel lines connect. If you find it don't waste any more time looking for the High and Low fuel adjustment screws (there aren't any) this is the only adjustment other than the throttle adjustment screw you'll find.
4. Start your blower allow time for it to warm up and advance choke as far open as you can without stalling motor (mine just suddenly wouldn't run in anything other than full choke).
5. With motor running, adjust the screw to improve operation. Depending on your initial choke setting you may have to adjust, open choke to next position and fine tune.
6. Note- clockwise reduces fuel to carb, while counter clockwise increases it (if it's stalling when you attempt to throttle up it's starved for fuel) I'm sure there's a tool designed so that some tech can charge you 100.00 to turn the adjustment screw 1/4 turn but I found that a pair of fine needle nose pliers did just fine. Pay attention to original position of the V notch and what adjustments you make ( I tend to make 1/4 turns and fine tune from there) so you can always go back to your starting point. Note I'm not a technician so I can't say this the fix for your machine but it worked on mine.

Ryobi straight gas trimmer, runs rough at idle and up to 1/2 speed, but great at full speed. Bought a reconditioned one.


Here was my solution:
I was having problems with my ryobi cs30 weedeater also. It would start up fine on full choke, but i could not give it more than half throttle or ever take the choke off or it would stall out. I replaced fuel mixture, spark plug, spark arrestor/exhaust, fuel lines, cleaned carb, and still nothing! I was considering getting a better machine. Then i decided to play with the carb adjustments.(on my cs-30, they are two screws on the carb that have a "L" and "H" next to them) I dont think you can get the specialty tool for adjusting the carb unless you are a repair tech, so i just took a Dremmel tool with the circular cut-off wheel to the head of the specialty screws and made them into "flat-head" screws so i could adjust them with a regular screwdriver (if you dont have a dremmel, get one!) (As i was cutting into the head of the screws, i also cut into the casing protecting the head of the screws that was in the way, this does not cause any damage to the unit, that casing is only there to keep "un-certified" people from adjusting it for themselves.)
Now to the easy part: The "L" screw adjusts the idle fuel mixture and the "H" screw adjusts the full throttle fuel mixture. turning the screws clockwise make the machine run leaner (less fuel) and counter clockwise makes it run richer (more fuel).
-I started out by turning each screw 1/2 turn counter clockwise and started it up, then as it was idling, i started adjusting the "L" screw as i was moving the choke position to run, after a few full turns counter clockwise of the "L" screw, it was idling perfectly in the run position, then i did the same thing the the "H" screw while holding down the throttle and i got it to run perfectly in the run position. Now it is running way better than it ever has. I hope this helps everyone.
Good Luck!
* For this specific problem, i would say you should probably just adjust the "L" screw and hopefully that will help

I wanted to know how to turn down the idle on my 1981 XJ 650 Maxim. Every time I come to a stop in first gear the engine races. At first I thought it was the choke. I don't know anything about motorcycle...


hello
if you were to look upward under the carbs, about center between the middle two carbs you should notice a screw with a larger head on it. this is the idle adjusting screw. hope this helps.
