Question about 1993 Suzuki RF 400 R

Idle screw seems to have no effect on revs? I must have turned it 30 times in each direction and it seems to do nothing to alter the idle level? Am i doing something wrong? :0(

Check you have free play in the throtol cable, if its tight it will hold the revs up also if the carb is sticky it will do the same thing

    well you never sead if it was high or low???

    ok,,me thinks then its the slow running jets (tickover jets) in the carb blocked up thats why it only runs on choke, as soon as the choke it turned off the bike cuts out,,,strip down the carb flote boles and spray some carb cleaner into all the jets you can find there,,, DONT go poking bits of wire into any of the jets as this can bamage the jets,,,it may still cut out on you untill you reset the slow running screw up again,,, there is another way to try to clear the jets and that is,,,,,, take off the air filter so you can get to the inlet on the carb,,, run up the engine, give it a bog rev and place your hand over the carbs the vacuum from the engine may just **** out any dirt from the slow running jets and clear the carb that way do it a fuw times on each carb,, (best done both at the same time) but you need extra hands to do it this way,,,and it still may not work for you, only striping the carbs down is guaranteed to fix it, have fun, drive safely,,,

Husqvarna 61 vibrates badly when idling.Various things keep coming loose. Tried locktight. 2nd problem is slow to idle from full revs, sometimes won't idle, will cut out when turned chain side down.


Could be a fuel tank vent issue, air leak in fuel line. Husqvarnas love rattling screws loose. Try altering the idle by turning the 'I' screw clockwise.

Stalls rough idle


You have a vacuum leak that is altering the air /fuel mixture and producing high revs. Make sure that all the vacuum lines are connected including the one to the distributor. Turn the idle mixture screws all the way in then back out 2 1/2 turns . That should get the engine running enough to do a final tune of the carbys.

1985 Toyota tarago 3y engine idles rough and seems to be pumping way too much fuel into the butterfly. Any suggestions on what to do?


There should be an adjustment screw on the side of the carburetor, controlling how much fuel the carburetor lets flow into the engine. You should be able to turn this screw with a small screwdriver, one direction lets more fuel in, the other lets less fuel. Its a guess and check on how much to turn it, do a little bit at a time until the idle clears up, then make sure the car runs correctly with your adjustment.

How many turns of the carburetor air fuel screw is the best setting for yamaha fz16? All stock parts, no modification made on the motorcycle yet.


The air screw on any motorcycle is adjusted to obtain the highest, smooth idle then turn in about 1/4 turn. This is the ideal setting for this screw. Simply put - this screw alters your pilot jetting and has very little effect on anything other than idle to about 1200-1500 RPM.

1998 Honda Civic Manual When in gear and accelerating the car makes a high pitch wine, which has gotton worse thru time. When at idle and under rev in idle there is no sound at all.


Well for one thing stop driving it before more damage
occurs. If it's not a problem with the transmission, you
may have a bad wheel bearing or cv joint. If you want
to check the wheel bearings, get up to speed and steer
left and right just enough to alter direction. If the noise
lessens or temporarily goes away, it's the wheel bearing.
Also check you gear oil level in the transmission. If no
noise in idle, I guess you can rule out the engine.

the idle is controlled by the computer and the idle speed motor if the idle is too low the first thing you should do is check for a vacume leak as this will directly effect the idle or revs as you say

Need to know then factory settings for the carburetor on a 78 it 250 e...how many turns out for the idle and how many turns out for the air/fuel mix?


I have the H model and set mine at one and a half turns out from stop. It waivers a little from summer to winter but only by a fraction.

As for the idle speed, when bike is warmed it will idle a little different to when cold and using choke.

Personal preference really, without a tacho fitted, I set it so she idles easy when cold. Once she's warm, idling is generally not used!!

To balance the two, warm engine and hold throttle at your optimum idle speed. Screw in idle adjuster until it engages base edge of carby slide. Release throttle and screw in/out fractionally to test if revs rise/fall. Set at optimum and then turn air mixture screw in/out till revs are highest (without using throttle). Then reset Idle screw back out to bring revs down to optimum level.

Tip, use a little thread seal on the idle screw as they have a nasty habit of unscrewing and leaving a hole in the side of your carby...sure fire way to lean right out and burn a hole in your piston when riding.

Cheers.

Won't idle until it is warmed up


Depending on the type of intake system, if it's a normally carburettored bike, there is an air mixture screw on your carby(s). Set this screw at one and one half turns out from being screwed to stop. Run bike till it is warm and set IDLE screw or throttle stop at optimum idle revs. Without using choke or throttle, turn the air mixture screw slowly in or out till revs build to highest level. Reset idle screw or throttle stop to set revs back down to optimum level as before. If this does not cure your problem, depending on if it's a 2 or four stroke, single or multi cylinder engine your problem may be one of many from fuel ratio, valve rocker clearance, ignition, plug range etc....specify make/model for proper info.

Husky 350 chainsaw idle to high


First there is an throttle idle screw that adjust the amount of throttle at idle try turning it ccw until it idles down. If this adj is at its lowest level then adjust the L screw until you get the idle you want. Then try to rev up it should rev up without hesitation if not hold down on throttle untill you get max rpm it it tries to cut out etc. at high rpm adj. the H screw until you get max rpm. then adj your L screw again for proper idle. You may need to do this back and forth for awhile until you get max. performance.
