So the cam was worn out, but what about bearings, timing, cam gears, valve lifters, and valve clearance. Basically if the cam went bad I'd think you'd have other things broken too unless you'd checked that too.

If you did. Another possibility is the ignition coil. This is a little easier to check, so actually you might want to start here. Use a multimeter and check for resistance as specified by your workshop manual.

Are you adding oil to the gas? (32/1 = 4 ounces per gallon)
Do you still have spark? Install a new stock spark plug.
Clean the carb, but follow these steps >

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 two screws 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 screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. 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. Let the bike warm up then set the idle speed. This process should get you back on the road.

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.

Please rate this solution. Thanks!

if you are getting gas, it's probably too much. is it flooding the motor. make sure your float level height is okay and that your float needle valve assembly is clean and not sticking. if you have an electronic choke, try disconnecting it. it might be malfunctioning. also a possibility your valves need to be adjusted.

My troy built riding mower won't run full throttle it only run at about half throttle


if it runs good at half throttle, it just wont throttle up it sounds like the throttle cable has slipped. you might try to adjust it to get full throttle back .but if when you turn it up to full throttle and it dies then you have a choke, carburetor, fuel line, fuel filter or fuel tank problem. hope this gives you an idea.

MC Dies upon ANY throttle application. HELP!


Odds are that if it sat for a year with fuel in it, the carb may be gummed up. Opening the throttle will cause an immediate engine stop if it is not getting fuel.

I'd recommend a "clean out the carb" project, including using air to blow out allof the small orifices.

Will only idel with choke all the way open


Check the quality of the fuel. If the fuel quality is good you may need to clean the carbs.

Starts and idles but has no power. What might cause this?


Its either needs the fuel system, including professional carb cleaning, or there is a ignition system problem.
Its probably the carb!!!!!

Won't start unless spray fuel change fuel pump did'nt help when it starts idel rough throtle up slowly it go about 3000 rpm start trying to die if you floor it from idel it will die but spray fuel...


Then its got to be a problem with the fuel delivery. You need to check that you're getting fuel from the tank.


1) Does fuel get to the filter? If not, is there an airlock or debris in the fuel pipe
2) Does fuel get past the filter? - If not, replace the filter.
3) I'm not sure if you have a carb. or injectors, but one or more of the injectors could be blocked. If a carb., fuel inlet jet may be blocked.
4) Finally, is the air filter good and clean.

Bogs down & spits back through carb.


Sounds like you may need a valve job. Have you been keeping the valve clearances adjusted? It's important to do that on a four-stroke engine. Check your compression to find out if the valves are ok.

Idles but won`t accelerate


Change fuel filter.
fuel pump sounds fine.
Check for kinked or blocked lines.
If it has a fuel recovery cannister service it.

Carb problem


Sounds like a problem with the main jet. Make sure the carb is cleaned of all the gunk from old fuel. Idle jet ok but if throttle opens too much air will kill engine if the main jet is blocked.
