SUCCCKKK IT!!!!!!! ha j/k you just flip it upside down and the gas will run out the overflow valve. :)
Very carefully
it is hard trust me.
pull the gas line off of the carburetor and let it drain.
run the engine out of gas!
What is the seat height of an 1989 suzuki rmx 250?
Although I cannot be specific with this make and model, this trick has worked on numerous vehicles over the years. Disconnect the fuel line and unscrew the drain plug, which is located on the side or bottom of the carburetor bowl. Drain as much gas out as possible. Also drain and clean the fuel strainer and clean it with carburetor cleaner. Now either spray or pour carburetor cleaner into the fuel line and let it drain through the carburetor. At first it may not drain, but as it removes the varnish and gunk it should soon begin to flow. For really stubborn and a through cleaning of the carburetor you can replace the plug and fill the fuel line with cleaner and let it sit. I've done this in chainsaws, boats, bikes and cars over the years and have always fixed the problem.
If you're lucky, there should be a drain plug for the float bowl (the bottom portion of the carburetor). Put a rag or something under the drain plug and then remove the drain plug, letting the gas/water flow out onto the rag. While you're at it, you may want to flush the carburetor with CRC Carburetor Cleaner, or something comparable. Give the cleaner time to evaporate, then put the drain plug back in. (Note: older outboards can have high speed needles where the drain plug should be. You can remove the needle, just make sure when you put it back in, it is in EXACTLY the same configuration it was in before. Also, DO NOT screw the needle in all the way to where it "bottoms out," as this may damage the needle permanently.) Water in the carburetor is NEVER good, and MAY require you to rebuild your carburetor to make sure that any corrosion/gunk has been thoroughly flushed out.
There should be a screw in the bottom of the float bowl on the carburators.
By removing the drain screw, or depending on the model, the fuel supply hose for the primer. Both are located on the front, lowermost area of the carburetor bowl. Once removed, the fuel will flow out of the carburetor.
easily unattach the hose coming from the tank leading to the carburetor turn the gas ''on'' and drain and then turn to "reserve" and drain the rest of the gas.
open up the float bowl drain screw and don't forget the reservoir (bottle) under the drain tube below that the hose that connects to the petcock off the drain screw.
Probably your float valve is stuck.
