While it COULD be the float level is set too high, if you haven't had the float bowl off, more likely it's some crud in the fuel got stuck between the float shut off needle and it's valve seat.
This doesn't allow the float needle to shut off completely, and fuel will keep coming into the float bowl, even though it's already full.
This is more pronounced with the engine shut off, and sometimes at idle, and less so as the engine revs increase.
This is because the faster the engine is running, it's burning more fuel, and better able to keep up with the overflow.

    Good suggestion! however, it could well be your carburator float as well. When not adjusted properly or defective will cause leakage. Look for the adj, specifications and check it. If no specs are available and you happened to have two carburators and, one is not leaking. Compare their mesurements. Remove the carbs bowls and compare them by, checking the drop adj and level adj. In other words mesure from the float to the carb housing upside down (level) and the drop from the float to the carb housing (upright position).

SOURCE: i read that the bolts after an oil change have to

All bolts on any type of machinery or vehicle have what is known as a "torque value". This is a value measured in foot pounds, inch pounds, newton meters, or whatever scale is used in the country you live in to gauge how tight the bolts must be tightened. This serves two purposes. First, it prevents damaging of the threads on the device. Secondly, to ensure that any warpage caused by tightening of the bolts does not exceed design specifications. Now, from a practical point of view, most bolts that were loosened during an oil change can be tightened to a reasonable tension and you will be safe. Just don't over tighten them but don't under tighten them either.

Gentron 10000w generator has a leaking carburator


Your carburetor float valve may be stuck open. You'll have to remove the carburetor, remove the sediment bowl at the bottom of the carburetor (where the float is), and check the float. Is it filled with gas? Replace the float if it is. If the float is dry inside, then remove the float and clean the needle valve & seat. (be careful to note how the float pin, linkage, spring, etc. are positioned so you properly reassemble. After cleaning & reassembling, turn the carburetor upside down & try blowing into the gas line connection on the carburetor. You shouldn't be able to blow air. Turn the carburetor right side up & repeat. If you can blow air into the carburetor's gas line connection, the float valve & seat are properly working. Reinstall the carburetor. You should be good to go.

Carburator leaks gas when cycle is started or running from what looks like vent hose?


Sounds to me like your float valve is obstructed by some debris. This is causing it to stay open and leak fuel. Better it leaks to your vent hose than it leaks in your engine and contaminates your oil.

You need a proper carb cleaning. Not some run in the gas tank sh*t. If the tank wasn't full when parked, chances are there is rust in the fuel system to get this out you need to disassemble the carburetor and thoroughly clean it.

Try not to ride the bike til you do this. It's a fire hazard.

I read that the bolts after an oil change have to be tightened at a certain strenght it that absolutely mandatory? honda falcon nx4


absolutely is a relative term, If you want it to stay in top condition. Its more of a scheduled maintenance. If you do it every time the oil is changed then you won't have the vibration causing bolts to loosen.

Turn on the gas knob. Light a match and hold it above the burner at the back. Press the switch inside the oven at the front of the base and hold it in. The burner should light and after about five seconds you can release the bottom switch and the oven should stay alight.
