SOURCE: XR 70. Idles fine. Won't throttle up just dies. Changed Plug, gas, cleaned carb...what am I missing

ALWAYS have a fire extinguisher at hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

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 a new stock NGK spark plug and try to start the engine. 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. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slides back in the throat of the carbs, move the clip on the jet needle one notch lower. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.

Please rate this solution. Thanks!

SOURCE: my honda xr 250 mototrcycle wont idle

Cleaning a carb will not change the jetting. The problem is in the pilot jet. This jet regulates the idle. Pull the carb off again and re-clean it. Remove the air screw and the throttle screw and spray carb cleaner into every hole you can find. Pay special attention to the air screw hole. Now put both screws back in the holes they came out of and turn them inward until they LIGHTLY seat. Now back each screw out one and one half turns. You are back to factory settings now. Get the pilot jet cleaned out and the bike will idle.

Those bikes can be a pain to start after they've sat awhile. What always worked for me was twist the throttle a bunch. I mean make sure its flooded. Then lay the bike over on its left side until the gas runs out the overflow. Stand it up and lay it down until it stops running out. Then I squeeze the decompression lever and cycle the motor. Now just barely pull on the decompression lever to open the valve just barely. Get it to top dead center and give her a good kick with a twist of the throttle. Becareful it could kick back.
This technique works for when the bike stalls when its hot. Most important part is if you think its flooded lay it over and start the process over. Remember your XR has two carbs and will flood QUICK. After some practice you'll be able to hear it in the exhaust pipe if she's flooded or if she trying to come around. Trust me. I have four of these bikes. Two 83's, one 84 and my beloved 85.

I have a 06 honda trx250ex put new gas and oil in it and plug and battery and iit turns over but wont start but when i put started fluid in where the plug goes it starts for like a second or so and quits...


your problem is a clogged carb. clean float valve, main jet and idle circuit with a can of spray carb cleaner.

disconnect fuel hose at carb and see if gas flows.

reconnect hose and open float bowl drain valve. If no gas tap on side of float bowl with plastic end of screwdirver to free up float.

still no gas? remove float bowl and try to shoot carb cleaner into the fitting for the gas line from tank.

if gas flows now then put it all back together and it should run

if not then remove carb and clean carb passages, main jet, idle circuit.

I have a 2003 xr 80 dirt bike. The spark plug is new there is gas and the oil is good and it wont start. Should i clean my carb?


yes, clean out the carb if you add gas directly to the carb intake, and it runs for a few seconds and shuts off, then you know you have a gas supply problem at the carburetor.

I have problem starting my xr 250(enduro)getting good spark plenty compression,fuel getting thru and carb all clean, ?? have changed cdi unit(original duff) but it was off mtx 125 but gives good spark,...


If you are getting gas than you have an air leak somewhere between your carb and the head. When the bike is ideling take a can of wd-40 spray slowly around every possable connection. ( rubber boot & where it bolts to the head ) When it sucks in air and wd-40 it will speed up and reveal the air leak. The boot itself could have a crack in it.

Honda Pressure Washer HP 5 not starting


You can try spraying some carburetor cleaner into the carb. If it starts for a minute, your carburetor need cleaning. When you added new gas did you remove the old gas first? Is the air filter clean?

I got a 1995 cr250 dirtbike and i have a problem starting it it wont start but keeps back firing the bike has a bran new rebuild it allways had a problem starting it. but now it wont start i took the carb...


im thinking if it has spark and getting gas and has compression, the bike will run. sometimes a "WEAK" coil will give a good spark, but under compresion its not enough to ignite the fuel. if thats not the case, take the air filter off and spray starting fluid into the carb and with NO CHOKE, give it full throttle and kick it over. if that dont do it try compression starting it, tow it for some distance if you have to. if that dont do it, then there must be something wrong with the carb. jets, fuel air adjustment. thats all i have. good luck.
