Try a new spark plug. if u fowl out a plug some time they will not fire under compression.2 strokes need. fuel,fire and air, very simple engines.it is possible crank seal are bad .that doesn't allow the engine to create vacuum in the crank case.thus fuel and air will not make it to combustion chamber.

I have a 2003 honda cr 250r 2 stroke,It will not kickstart,you can bump start it and it starts right up and runs really good.when you try and kick it it leaks gas out of the carborator.


Usually, a leaking carb is because either the float is set too high, or there is some crud stuck between the float's needle valve and it's seat.
Either one will not allow the float/needle valve to shut off the flow of gas when the float bowl get's full.

This should be your carb:

The floats are the 2 large square items on #5 on the illustration.
Item #3 is the float needle valve.
Item #4 is the needle valve's seat.

Cr 250 r honda dirt bike wont start


What did the spark plug look like when you first took it out? Was it black/wet/sooty or was it a light tan/gray color. If it was black/sooty, then I would guess you need a coil. I know you said it had a good blue spark when you checked it, but if you poured a little bit of gas in the cylinder and it still wouldn't fire that would be my first place to check. If it ran briefly after you poured a bit of gas in the cylinder and then died, then it's a fuel supply issue. Remove the line that goes from the gas tank to the carb and make sure you have gas at the carb. If you have gas, then I would remove the carburator and take it apart making sure all the jets and passageways are clear. Use carb cleaner and an air attachment and if you still can't get it out, use a small wire to clear things up.

Reassemble and it should run, otherwise report back and we can go to the next step.

Ran bike out of gas, when started again it back fired and never ran right again.


Since you ran the last drop of gas out, check the fuel filter and check the float bowl to ensure you did not suck garbage into carb.

I have a 12.5 hp Briggs&Stratton. The float is stcking in the carb and gas is just pouring out. What can I do to fix this ?


The small needle valve which is actuated by the float could be stuck open because of some dirt under it.Remove the carb and pull the float bowl off and you will see what I mean.Sometimes you have to replace the needle valve since they do wear out and cause this problem.

2002 CR 250-has gas on carb,new plug and only starts with a squirt of starting fluid and dies instantly.


Best would be to clean the carburator, it seems the gas doesn't enter the combustion chamber, the jets could be blocked.
Check the valve clearance too, not bad to take the compression test of the cylinder.
