Usually any fuel leaking out of the carb like that would be an indication of a sticking or defective needle/seat and or float mechanismn. Clean thoroughly with carb cleaner and or rreplace needle/seat/float and bowl gasket.
Your carburetor is loading up. Or your needle valve is out of place or stuck.
Seals, or float level.
There can be several different causes. Basically, it can be the ignition system or the carburetor. Too much oxygen in proportion to gasoline will cause backfiring. Also air leaks in the hose that connects the air intake to the carburetor. A faulty CID can possibly cause backfiring, however this is not as likely as the cause I mentioned first. There are other possibilities, but I would suggest a geneal tune up and inspection of the spark plug.
Yes. to solve the problem strangle the fuel pipe to cut flow of fuel and persistently start the engine it should solve the problem.
possibly a leak in cooling system
obviously the honda XRM 110 cause it has a small engine than raider 125... more speed means more gasoline consumption...
Engine overheating will cause the anti-freeze to surge into the overflow tank. A blown head gasket will also cause the anti-freeze to surge into the overflow tank.
Float may be stuck in carburetor, or you may need to turn the petcock to the off position when not riding (if applicable). ~RC@HD~ ANSWER: Another posibility is that the gas cap is not venting correctly and when the bike sits in the sun, presure builds up in the tank forcing gas out of the overflow vent in the carb.
Yes, you can adjust the toilet clog to clause your toilet to overflow.
Antifreez, make sure your mixture is right
Depends on what type of overflow and what it services and whether it is constantly happening or intermittent.
Yes it could if you in fact have a carburetor. Carburetors were fazed out during the 1980's.
