Never owned a H-D, but every bike I've owned has the gas tank vented through the fuel cap.

FUEL BLOCKAGE FROM TANK TO FILTER


I was mowing along on my John Deere LA145, which had about 200 hours on it, and it slowed down then died. Before it died, it was acting like it was losing power. It felt like it was only firing on one cylinder. I waited a bit and it restarted after a lot of cranking. I made a couple mowing passes, and then the same thing happened.

Because I have mowed commercially for many years, I know my equipment inside and out. This mower was in top running condition and should not have been acting this way. There were no engine misses, no backfires and it was not normally hard to start. I knew the carburetor was clean, the coils were good, and the plugs were new. The fuel filter was recently changed. I got off, lifted the hood and gave a general inspection of the engine compartment. I noticed the fuel filter was nearly empty. I pulled the hose off the tank side of the filter and saw there was no flow.

The gas should gravity flow from the tank to the filter, if the tank has a good supply of fuel. Not that I recommend this practice, but I have no problem with doing it myself....I wiped the hose off and blew air back into the fuel tank. It helps to take the gas tank lid off first. After I got a good flow of air going back into the tank (it required several lungs full of air, you can hear the bubbles) the fuel began to gravity flow back through the hose at a decent clip. This fixed the problem. There is likely silt build up in the tank and it settles at the output port blocking the flow of fuel.

The problem repeated itself several times last summer. Back at the shop, I used compressed air to blow the line clear. The problem has not shown up in quite some time.

Why is my riding mower dying out?


In my experience there is only two situations which can result in stopping as described. One is a partial fuel blockage which simply results in the motor using all the fuel available and then needing more. Remedy is to check the fuel filter and flow bulb [if there is one fitted] and remove and clear the whole fuel line from the tank to the carburettor. Also clean the nedle valve and the carburettor completely. The other possible problem is an expired ignition coil which can heat up and cease to function. It cools a little and works OK until it takes time to heat up again. This is not common but can be very hard to track down. Try the fuel fix first as it is at least twenty times more likely.

Why would the engine die after running fine for 20 or 30 minutes. I think I have eliminated vapor lock, bad fuel and overheating. Could it be running too rich or to lean? When I disengage the blade


sounds like you have carb troubles,not getting enough fuel,take carb off and clean it good make sure all holes and ports are clear! also I would put new plug or plugs in it,I can tell you how to see if its the carb plugged up when you have it running and you are about to engage the blades pull the chock out sumwhat to make the engine run rich then engage blades if it dosent stall and runs good then you are experiencing a dirty carb! good luck!!

Motorcycle complete loss of power and bike dies


check that the tank cap is venting and not causing a vacuum in the tank and lack of fuel to the engine.

Hit the gas and the engine almost dies. Idles and starts fine. Changed the spark plug - no change.


What kind of bike? It sounds like clogged carbs, if pilot jets are plugged from lack of service or sitting for a while then your bike could still start but will fall on its face when opening throttle due to lack of fuel, solution=clean your carbs thoroughly and flush your tank.

My Yumbo Dakar 200cc bike dies after riding in 5th gear reving medium-highish for a couple of minutes, it usually just dies after i hit the clutch (coasting), but on long runs @ around 50-60mph in 5th gear...


G'day,
I have a couple of ideas what may help.
First I would think it was starving for fuel.Or maybe an unusual ignition system fault- So how do we find out?
Well-you could try checking the bike for spark immediately after the bike stops.
Remove the spark plug-Re-fit to the cap-place plug resting on metal where you can see it(DO NOT HOLD PLUG-HIGH VOLTAGE)-kick over & check for spark.If theres no spark-try a new plug but if the problem persists then the bike has a faulty ignition(coil,cap,plug,stator.ignition/kill switch,wireing)
I think it is more likely starving for fuel.
A faulty fuel tank filler cap vent or carby vent tube pinched or blocked.
To check the filler cap-ride the bike & when the problem just starts-quickly crack open the fuel tank filler cap to let air in/out. If bike runs ok then the cap is blocked.
To check the carby vents -just look at them & make sure none are blocked or pinched.They usually come from each side of the carby & one from the bottom(usually clear or semi-clear hoses).
I hope that this helps you with your problem.
Regards Andrew Porrelli

Engine Dies in Idel


being a certified mechanic has its advantages. there are multiple causes for that problem: lack of air or lack of fuel.
make sure the air filter is mostly clean.
check throttle plate (where air filter tube goes into motor), most likely black with soot and carbon. clean with tooth brush and gas, wipe off with clean rag. repeat ultil CLEAN.
low air flow past plate when closed (idle) will cause stall condition.
dirty throttle body is a common problem with lots of cars. causes engine stall.

dirty fuel filter will also cause this problem.. low fuel pressure at idle.

I also believe that your car is equipped with an idle air control valve. (regulates a bypassed air flow to motor at idle) this valve may be stopped up or non-functional. have local shop take a look, but there are ways to check valve if you consider yourself mechanically inclined

Breaking Down


The problem may be a pinched fuel or vacuum hose, or a weak/collapsed vacuum hose. The problem may be varnished fuel/carburetors. It may be an electrical problem: loose connector or defective conductor. I cannot help you other than this without having the Duc and performing a few tests. The Monsters are fun to ride.

It wont start


Sounds like your tank is not venting correctly thus too much pressure int he tank is starving the bike Checking the routing and connection under the tank and fingers crossed she will be back to normal
