SOURCE: bike runs at Idle but dies when given gas

have you changed the fuel filter? you are not getting enough gas, are jets squeaky clean? there is a good fuel system cleaner in the USA called Berrymans B12. put some in the tank warm up bike then let it stand overnight and see what happens. if still no luck repeat process. if you still have same problem then get new fuel filter

good luck

I have a supermagna and used fuel stablizer once and it wasnt fit it gummed my carbs up,ive cleaned mine often and it isnt rocket science,remove the tank airbox assembly,loosen up the boot flanges that hook the carbs to the motor(ones on carb)then remove the carbs,then the cables,choke and throttle,do not remove carbs from assembly(leave all 4 together)remove the bottoms and tops of a carb,removefloat and jet,then remove all the brass jets and clean them so you can see through holes,,blow out all the holes in carbs,and reasemble,works for me every time,about two hours to do,good luck

SOURCE: won't idle steadily

Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)

SOURCE: Will not run without choke

have you checked for vaccuum leaks at the intake manifold? you can check by pouring water over the gasket area when/ if you get it running!

SOURCE: 2005 kx250f wont idle.will idle fine w/choke

the fact that it idles with the choke on indicates that fuel mixture is the problem here remove the mixture screw completely check that the o ring seal is not damaged & that the end of the needle is not worn or bent if either of these conditions are obviouse replace the damaged or worn parts general rule of thumb with mixture adjustment is 1&1/2 to 2 turns out give it a try

Scooter has 40 original miles.New,old gas, I put innew gas. It starts,idles only, if I give it gas it stalls and won't run..

If the old gas sat in the scooter for a long time the carburetor may be lacquered over and may need to be cleaned. If it has a manual choke see if adjusting that while running will allow it more RPM.

You need to pressure test the carb, if the needle is leaking you will never get to run well, if you have fitted a new rubber tipped needle and it still leaks you will have to replace the carb, the later carb was a Zama rather than the Walbro, it made the saw run so much better.

How hard is it to remove the carb on a 1995 Harley Sportster. The bike has not run in 4 years. I got it started but it won't idle under 2000rpms and runs rough. I think the carb needs a good clean

Very easy to remove and disassemble the carb. Just keep track of every thing you did and where it went. It would be best to get the manual if you can.

hi there harryandmeli
sounds like you still have a restriction in your carb or the float level is not right
check all the opening s and jets carefully, particularly main jet and emulsion tube air bleeds
and the idle air bleed , and idle jet, is the tank clean and no water ? , is the tank breather working ?, make sure gaskets at carb flange are ok - no leaking of air , make sure air filter is not blocked ?

provided compression and spark ok,( spark should jump a 6 mm gap minimum ) to pass a coil test and fuel flow from tank to carb is good , these engines have hydraulic valve lifters and like 10w/30 kohler oil , everything being = engine should run good

remember F A C T S

F = Fuel , A = Air , C = Compression , T = Timming , S = Spark

take a look

cheers hope it helps

Husqvarna 51 died and wont restart

hi
if you have a good compression,a strong enough blue spark and carburetion for the fuel air mixture try priming the engine(put small amount of gas in the spark plug hole)then start the engine.If the engine runs only the gas you put inside the cilinder there is a carburetion problem to find and fix.
let me know regards savumihai71

I have a husqvarna 55. I put in a new carb, coil,

Preset both needles about 1-1/2 to 2 turns CCW from CW stop. Set H needle first after warm-up. At high speed, engine should 4-stroke with no load, but smooth out with light load(cutting wood). Set idle speed so that it will keep running, then adjust L needle so that engine tries to follow the throttle, but idles fairly smoothly. Readjust idle speed so that the clutch is not trying to drive the chain.

Mariner 25 hp 2 stroke hard to start then quits and won't restart

It sounds like the float is sticking in the carb. Since the carb is higher than the fuel tank it pulls the fuel in by vaccum of the engine. when running at high rpms, it can burn the fuel thats flowing into the carb, when you idle down, the bowl of the carb is filling up with fuel faster than the engine can burn it and causing it to flood. Then when it shuts off at idle it does not want to start back up because it is flooded. To make a long stary short, pull the carb and give it a good cleaning and your problems should be solved.

Hard start, trouble idleing

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install new stock spark plugs. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. This process should get you back on the road.

Please rate this solution. Thanks!
