Bulb Eater

I checked the fuel filter and its own.

you probably need your carb rebuilt. The membranes are probably bad

fuel filter must be installed, it works as a weight to keep the fuel line in the gas. the system must be airtight - good fresh fuel lines - if the fuel lines are difficult, they must be replaced. Also check that the cap is in good working condition - he must seal the fuel tank over there is a valve in the cap of which must function properly.

you need to rebuild the carb

Have you changed all the gas lines ... These smaller lines are bad on the ends fractionation .. Even if the lines looks good it does not hurt to replace them ....

There must be a blockage in the fuel line or a split / hole in it and you're just sucking air in the bulb. It is a cheap and easy to replace the fuel line and that could solve your problem.

The same thing happened to me. The fuel gas in the tank itself has been locked in an upward position so that it would not get gas when I pear.
