If you have gas dripping for the pipes you may have gas in you oil..I'd check it. Sorry to say you probably have to pull the carbs..unless you really flooded it yourself you have a sticking float needle or hung up float..both, floats set wrong or a leak in an o-ring seal that is allowing gas to flow in the intakes.

What the next post says is true to a total fuel system cleaning and rebuild is in order most likely..

After 11 years of not running I would saythat a few things would have to be done before attempting to start the engine. I would have sprayed the cylinders down with some liguid wrench or pb rust blaster and let them sit for a few days, then turn the engine by hand to make sure that it is free to turn.

I would say that the entire fuel system will need cleaning out (that includes the carbs). Inspect the fuel tank and see if it has rust in it and if it has lots of rust then the tank needs to be replaced or put a tank liner in it.

The fuel petcock should be removed and cleaned out also.

The fuel in the # 3& 4 exhaust and the wet plugs is more than likely caused by the carbs flooding over. The carbsflooding over can be caused by rust inside them, bad floats, bad fuel inlet needle & seat ect. The carbs have to be cleaned out and/or rebuilt correctly or you will have problems as such. The carbs most likely will have to be removed again and the rest of the fuel system cleaned to get it done correctly.

Good luck!:waving:

Hi,thanks for the reply,i oiled the bores etc,and checked the tank, fuel flow ,petrol pump and other things before starting,the carbs were cleaned by the person i got them from he knows his stuff so they should be sound,i cant help wondering why only 3&4 are leaking,is it possible they are not fireing and 1&2 are.

not likely they are on different coils and ignition sets. Gas leaking is almost always as I outlined above..

Check the bottom of the tank because it will have the most rust and that is where the gas gets picked up at. It does not take much rust to cause thefloatto stay open andleak. Check the float setting which could be wrong...that can cause it to flood over. Carb cleaning requires sometimes jet drills or wire less than .010 inch to properly clean out all the jets and the emulsion tubes. If all of the fuel system is not cleaned out correctly the carbs may continue to have trouble. To check 3 & 4 firing.... remove the plugs and set the metal spark plug shell onto the engine cases while plugged up, turn on the ignition andenergize the starter button a few times while watching for a spark. The float bowls are probably running over due to trash, settings, ect.:waving:
