finally sorted when I replaced both plugs. I've never come across one failing instantly before in 30 years of motorcycling (maybe that's because I ride old bm's!)

SOURCE: stalling when starting

if after the two mins ur putting the choke back in and the bike dies, it could be that your needing to adjust the idle speed.
it might just be set on the lower limit so that when ur bike isnt fully warmed up it struggles.

SOURCE: will only run with full choke and absolutely no throttle.

Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.

Use a couple of cans of Sea Foam.. best stuff in the world.

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

5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.

My Troy bilt 675 190cc was left out side about 3


First of all add some fresh gas. chances are it may have leaked off or is gummed up..then remove you plug and with the wire attached have someone hold the spark plug firing end against the engine head an pull or if electric start spin the engine you should see spark between the gap or from the plug to the engine head..if you have spark cover the plug end with tape then spin the engine again tto clear the cylinders of old gas.. clean clean or replace the plug..before replacing get some starting fluid spay some in the plug hole and some on the plug and replace the plug..and try to start..from there you may want to spray a little in the carb...just be careful it is very explosive so easy on the spray...and keep clear if the carb area. May have some backfire....if this starts but won't keep running try it several times. If nothing your carb will need to be cleaned..good luck..

Does a ***** boy 50cc have a reed valve? Bike


Hi first thing what is the bike second thing is the engine a 2 stroke, if it is 2 stroke it most prob. has a reed valve, check that the carb needle valve is working as it should, then drain the cylinder and crank of fuel check the plug sparks, leave the carb off and put a small amount of petrol in it, try and start it if it fires once or twice, then it should start with the carb on it, if not there is a problem with the carb. good luck.

Mower engine not firing but brand new spark plug and clean fuel


Did you varify spark? How long was it sitting? if you have spark, may need to clean out carburetor float bowl. inspect it for sediment that could be clogging jets. clean carb. with todays gas containing 10% ethenol it really eats up the inside of fuel lines so may want to replace the fuel line if your mower is getting up there in age. If you have spark try spraying some WD40 into the spark plug hole , re insert plug and try to start. If it starts for a few seconds then you know its carb. good luck

Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.

The bike wont rev up, spits and sputters idles fine. carbs have been cleaned and sinked new plugs and fuel filter.


Hi, Marvin if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.
