Take the carb off and remove the screws that hold the float on. Once you have that apart, the float should be pretty obvious. Toward the back of the float (where it hinges) there is a small spring and a pin. Orientate the carb in it's normal position the float should be freely in the down position (this is when fuel enters the carb.) the pin should be pushed up. Now, push the float up (this is when fuel stops coming into the carb). The pin should fall. There should be some tension (very little) that makes the float want to return to the down position. If anything is out of order, order a carb rebuild kit. If the carb is flooding, this means that the float is getting stuck in the down (open) positon and not floating. This happens very often with older floats. Newer ones are plastic and won't get fuel logged or covered in suit. Let me know if this helps and what happens. Good luck

My 2002 ktm125sx runs awesome revs great until carb bowl fills up then it floods and runs terrible I turn the gas off and it'll scream until it starts running out I've cleaned carb checked float

Hi, Dewayne and the usual suspects are:
1. Dirt or other foreign matter between float valve and its seat.
2. Float valve sticking.
3. Float valve and/or valve seat worn or damaged.
4. Float misadjusted.
5. Float cracked, leaky or damaged.
6. Excessive "PUMPING" of hand throttle grip.

Gas floods out of the exhaust manifold

Stuck float valve, letting too much fuel into the carb. Try taking the bowl off of the carb and checking to make sure that the float needle moves freely up and down. If there is evidence of gumming inside the bowl you will want to get some spray carb cleaner and clean everything in there thoroughly.

I cleaned the carbs it ran great for 10 miles and then began flooding.replaced the gross jets in float bowles. ran good but had to pull of carbs again to fix float bowl leaking now it floods so badly it...

Sounds like you need to check the needle and seat for dirt etc. or one of your floats may be sticking. A simple way to check is to connect the fuel pipe to carbs upside down with float bowl off and you will see if it is leaking or not. If that is ok then make sure that the floats are not sticking or holed. Test again by inverting the carbs again with no fuel in them and you should not be able to blow into the chamber until you turn the carbs to normal position. Hope that helps.

1970 shovelhead 1000 cc how do u adj.tihe carb ; i have cleaned out carb an now for some reson it's acting like it has jumped time an is flooding out why

The timing has not changed just because you cleaned the carb. If it's flooding, the needle and seat are not sealing like they should. If this is the case, you should be seeing fuel coming out of the overflow tube when the engine is not running or the fuel flowing into the carb. You didn't mention what type of carburetor you are running on the engine. The original Keihin carb is notorious for doing this. I've worked with them all day long trying to get one to quit flooding. It's as if when you clean the carb and take the float out, if you rotate the needle or something, it just will not seal. I've had to lower the float setting on many occasions to get it to stop. Do not lower the float setting over 1mm.(0.040") as you may start to starve the engine for fuel at highway speeds. If the carb is an S&S carb. Check the float setting with the bowl held upside down. It's shoudl be 1/8" into the bowl from the gasket surface. If it's a Bendix carb, you may not have the float spring in the carb correctly.

Good Luck

Hi ya got a old ish tiller in for repair, it is a ISEKI AC40 problem is hard to start & when it starts it will only run for about 10 seconds, so far checked plug which has a good spark, compression ok,...

From your description we will assume it is flooding. If you suspect float problem, check float level, holding the carb upside down the float should be parallel to carb body when needle seat is closed. On metal floats this is accomplished by bending the tab that rides on the needle, units with plastic floats you may have to replace it. Also remove float and shake it, should not be any gas in the float, this will make it flood. Also set carb adjustment screw at 1.5 turns out, may need a little tweek from there.

First of all i hope u have a gas shutoff to the carb from the tank. If that float needle valve is not closing, the gas can make it all the way to the crankcase through the valve ports and get to the engine oil. Shut off the gss supply to the carb. or if no shutoff is on the machine, undue a line and plug it with something. U may be able to drop the carb. bulb off (bottom of carb.) by not removing the carb. from the engine.
If so, take the (usually four screws) out on the top of the carb. that looks like they hold the bulb on. The bottom should drop off and the float will be exposed. Be careful with the gasket between the two pcs.
Now check your float, that's all u ask for.
