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.

My arctic cat 4X4 with a Mikuni BST 31 carb suddenly lost power and fouled the plug.New plug makes it start instantly and it runs great for 10 sec then fouls plug.Diaphram is good. Bowl not leaking

Pull the carb off and rebuild it, it either has a failed fuel inlet valve or a sticking float or a plugged jet from dirt in the fuel. If you are careful you can do this clean out with no new gaskets, use carb spray and compressed air. You may need a new fuel inlet "Needle Valve and seat". If you do find allot of contaminates in the float bowl you will need to clean the fuel tank and lines to the carb.

I got a 1990 kawi js 440 andf rebuilt the carbs and its hard to start and when it does it dies then the carb floods with gas and will not start again cuz of to much fuel do you know what is wrong

Your carburator bowl float is stuck in open position, or it is sticking allowing the gas to flood the engine.
Remove the carburator boal and try to clean or replace the carburator bowl float.

Die's after warming Up

Sounds like the carbs are dirty, The mail inlet where the float works to shut off fuel when the bowls get full has a screen just under the needle valve and there are stopped up with crud, Pull the bottoms off and remove the float & needle valve and the the seat and clean, If you see dirt inside the float bowl then remove the jets and clean them also.

I have a 2005 crf230f it started leaking out overflow from carb pull carb off cleaned and put back ran great for a while the started overflowing any anwsers

check the drain screw on the bottom of the bowl, check to see if the needle or float is sticking, and check the gasket around the bowl. i also reccomend instaling a 115 jet rather than the 132 honda offers. it's just too much of an increase from a stock 102

Mower ran out of gas now it wont start

Hi and welcome to FixYa, I am Kelly.

Carbs all have some minimal derbis in the float bowl. When an engine runs out of gas the float bowl cavitates and the debris that was just fine in the bottom of the float bowl is drawn into the main fuel jet located in the threaded area of the bowl nut. Remove the float bowl nut and bowl. Use carb cleaner to remove the debris from the main fuel jet orifice in the threaded area of the carb body.
(If the carb cleaner does not free the debris from the main fuel jet is can be unscrewed and removed for cleaning. Just make sure the screwdriver is a good fit to the brass slots of the orifice or you will never get it out.)
Make sure to clean out the float bowl and nut before re-assembly. This should get you going pretty quickly.

Thanks for choosing FixYa,
Kelly

Bike floods its self constantly, i drain the carb bowls, it starts then floods after not even 1 minute of running....

The fuel is probably flooding due to trash in carb, remove the fuel bowl,clean float needle,clean jet and the orfaces in it.(if dirt is in it clean the rest of the fuel system to keep it from happening again.) Spray cleaner does good.

Fuel Starvation - Float Bowl Carburetor
1) remove air filter assembly
*be cautious of tearing the mounting gasket. If it does tear, you HAVE to replace it. It is part of the priming system
2) remove the float bowl fastener. This is the main jet
3) carefully remove the float bowl, the rubber o-ring/gasket will not be able to be used if it is removed, you WILL have to replace it
4) using a spray 'carb cleaner'
spray up thru the center of the carburetor
spray and clean the main jet with cleaner and 'tag' wire
(tag wire is very thin, and can be used to clean the hole in the center of the main jet)
5) clean any debris from inside the bowl or carb body
6) re-install bowl and center bolt, air filter assembly

*if you need gaskets, your local lawn & garden dealer can supply. The kit is cheaper than individual gaskets, and all the parts needed to finish the above repair are in the kit.

Mass flooding piston cylinder

This sounds to me like a carb float being stuck open. Turn off the gas and drain the carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and clean it with a spray carb cleaner. Be sure main jet and float needle are clear. Clean the air filter then re-mount carb. Next Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Install an inline fuel filter. Turn the gas on, wait a moment for the float bowl to fill with gas then give it a try.
