I'm assuming it is carburated. Sounds like the float needle (seal) is not sealing. It will dry out when the bike sits up for a while. You should replace it or soak it in oil until it becomes pliable again.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. 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 two screws on the outside throat of the carb and spray into the screw holes as well.
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. Set the idle speed with the idle screw. This process should get you back on the road.

The crank seals could be going bad, but clean the carb first.
Please rate this solution. Thanks asimonton84!

SOURCE: running rough. no gas going to front plug.

If your plug is dry, then there is no fuel. This can happen for two reasons: No compression - be sure to get a compression tester and ensure that there is enough compression produced by the engine to enable the engine to run. More than likely, though, there is no fuel getting to the engine. When cleaning carburetors, it is important that you use a chemical dip. Spraying carb cleaner through it is not enough. Be sure to disassemble completely: fuel float and its needle and seat, all jets, all emulsion tubes, all air cut off systems and accelerator pumps, all enrichment circuits (choke), vaccum slide and diaphragm, all air jets, and last but not least - the idle air/fuel screw. If this is the first time the carb has been taken apart you have to drill the cap to get to the screw. once everything is apart, soak all metal parts in the Berryman or equivalent chemical dip solution for at least several hours. After, run hot water, as hot as you can stand over all dipped components and blow out with compressed air. reassemble and enjoy.

SOURCE: Experiencing leak at manifold to head junction.

these type manifolds are made of a metal base and a rubber joint. the rubber is hermetically sealed to the metal part. over time, this seal can go bad causing a leak that is undetectable by the average person. if you say you have replaced carb and sprayed around the boot with a pickup in rpm's, i would replace the boots abd orings! this should solve your leand condition.

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.

Why can't it be started?

You have a fuel flow issue if the plug is dry. Put the choke on and pull it numerous times to try to flood it and see if it floods. If it doesn't than you have a blockage somewhere between the fuel tank and carburetor

Honda gc 190 starts then floods and stops. Wont start again till plug is taken out and dried then repeats same thing

Float level or a sticking needle valve, check float level as if it is adjusted incorrectly it can cause the main jet to allow fuel to flood through, the needle valve can do the same.

Not sure what happened i started my 97 cbr600f3 ran it on choke for about 45 sec. it started to die,so i eased the choke off it died and havent been able to fire it up since.any suggestions

Remove plugs to see what colour they are. If sooty then too rich / clean / install.
If wet then flooded, dry refit.
If clean and dry, starving lack of fuel.

Mower ran fine but was outside for ayear covered now it will not

Leaving a mower outside for an extended period will often allow water to get inside the engine (even covered). Try removing the plug and drying out the cylinder (compressed air blown into the cylinder usually works.) With the plug still removed pull the cord a few times andf try to get the piston to stop on the bottom so you can blow out the entire empty cylinder. I usually then put a squirt of WD-40 in the cylinder (not too much) and pull the cord a few times....then reinstall the plug and fire it up.

If that doesn't do it, try the WD-40 in the muffler (a couple short squirts)...also make sure the air filter is clean and dry...I would try to start it without the filter installed to see if that is the problem (just don't allow it run more than a few seconds without the filter).

1976 Dodge motor home with a 360 will not start.

You are on the right path. You gave away the answer when you said you can dry the plugs and then it will start and run for a few seconds before flooding out again.

To solve the problem (there seem to be two of them) do the following:

You need to stop fuel from entering the engine, either disconnect the fuel line from the tank to the fuel pump or route the output from the fuel pump to a gas can or back to the tank, just don't let it get to the carb.

Pull the coil wire, pull the plugs and spin the motor over so it can get dried out.
Pulling the coil wire should help reduce the risk of the fuel being blown from the cylinders from somehow getting ignited. BE CAREFULL!!!

Now dry the plugs and put them back in, plug in the coil wire and fire it up. Based on what you have said it sounds like it will probably start up (if only for a second or three). Now pour two or three teaspoons of gasoline into the carb and start it again.

If it starts and then dies that is a good thing. Do the two or three teaspoons and start it two or three times. This will heat up the compression chambers a little and help to dry them out a little better.

Now, at this point it runs fine (well as fine a 2 or 3 teaspoons will run it) as long as it has fuel, air and spark.

Hook up the fuel line again and start it up. One of two things will take place.

1. All is well! Great, it was just REALLY flooded.

2. It runs for about 10 seconds before becoming flooded again.... ****, it sounds like your "new" carb is flooding the engine. Find out how!

Good luck. I have used this "fix" a few times over the years. Normally the engine is REALLY, REALLY, REALLY flooded. Usually because the original problem happened on a hot summer day and the float stuck when the engine was shut off. The heat of the engine boiled the gasoline which in turn flooded the engine. The float stayed stuck when they came back to start it and TA DA.

Several times a little tap on the side of the carb "cured" the problem and a fuel additive was used to clean up the sticky float issue.

In one instance the 4 banger was so flooded we had to snake a hose into the cylinders and **** the fuel out. We must have sucked a quart of fuel out of that little '80 Mustang. We still ended up draining the oil (it smelled like it was full of fuel too) and we spun it over until it quit spraying gasoline all over. Man was that a mess!!!
