Bike been stood for a while, starts no problem but fuel comes out of the rubber pipes at the top of the carbs were the diaphram is

check replace the rubber seals under the injectors

have you tried starting with the air intake pipe/hose removed from the carb ? if still wont start i'd strip carb down and clean out the jets , not forgetting the idle jet at bottom of bowl , also check the diaphram pump is in working order , rubber diaphram still flexable not holed etckeep me posted if you wish

Hi... if you have vacuum cabs... Have you checked to see if the vacuum on the fuel tap is working correctly.. Take the fuel pipe of the carbs, put the fuel tap to on.. If its a vacuum tap there should be no fuel coming out. Put the pipe in your mouth and suck on the pipe, if fuel comes out then stops it seems to be working. Also check the diaphragms in the top of the carbs are not split or have any pin holes in them. You can do this but holding the diaphragm up to the light.. (If they are vacuum carbs).. You can aso check to see if the carb rubbers are leaking between the carbs and the engine.. You can do this by starting the bike up and leave it ticking over. Get some carb cleaner or WD40 and spray it onto the rubbers between the carbs and engine. If the engine pics up speed (revs go higher) then the rubbers need to be changed.. Hope this helps you out...

Good luck.. Tony.

the float valve that cuts the petrol off is not sealing so the carbs(s) flood into the air box then runs down the engine breather pipe in to the engine.dont use the bike as the enginewill be damaged. or if you have a diaphram fuel tap the diaphram has gone, take the petrol pipe off the tap there should be no fuel coming out when the tap on or on res if there isfuel coming out you need a new tap

hi, you dont say what bike this is, however the main reason for this would be at least 1 float valve not closeing, has the bike stood for a while, classic symptom, reason for not starting would be overfueling, normaly you will find a drain screw on each carb with a pipe for fuel to overflow, this would then be oviouse which carb is giving the problem as the fuel flows out of the problem carb overflow, your overflow tubes which are located inside the float chamber may be blocked, i would think that in this case a strip down of the carbs to check and clean as ness would be in order, in the same way the fuel will run out through the airbox it will also run into the engine, causing it not to run

This is a crack, pinhole or tear in the rubber carb diaphram or loose screws on the diaphram cap. The tear, pinhole or loose cap is killing the vacuum needed in the top of the carb to raise the carb slide to increase speed. Please rate my answer.

Hi Kevin, the fuel entering your airbox is likely coming through the vacuum hose from the top of the carby. You may have a tear in the rubber diaphram or the lip has curled or squeezed, allowing fuel to enter through the hose. If your bike is running alright otherwise, this is a relatively easy/cheap fix. The carby parts are available from/through all bike dealers and complete carby's are available secondhand from dismantlers or ebay at comparitive prices to the parts.

hi m8,,just to give u some things to check b4 i give yuh some more tips,, 1st, thing had your bike been stood 4 a while if so it would have been on its side stand at some point so 1 and 2 carb would have contaminated fuel in, work on those two carbs and make sure they have clean jets and float bowl,,while your in the carbs have a look at the diaphrams on top of the carb,, gently take one out and hold the diaphram up to the light to see if it has any pin holes,,, if there isnt then happy dayz,, it sounds more like fuel thats gone off in side the float bowl and blocked up your jet,, take the jet out,, and poke a pin in the holes ,try that mate,,

Hi Chris,

You can download the service manual for nix from here. trying to picture what you are looking at, but if they are the only rubber hoses coming off the carby, then they are most probably the fuel lines. If they come off the very top of the carby, then they may be breathers. The bike has a vacuum operated petcock also, you will need to have it in prime position for the carbs to fill. Then once the engine runs, if the petcock os working correctly, then you should be able to get fuel in on position. Just cranking it over will not created enough vacuum for the carbies to fill.,hence the prime setting. Happy to answer any questions you may have about the bike, A FixYa rating is a great reward for my efforts to assist you. Cheers
