Leaks fuel from air filter.and runs bad like to much gas


You haven't provided a whole lot of information, but it sounds like you have one or two stuck carb floats / non-seating float needles that aren't cutting off the flow of gas from the tank when the carb bowls are full. The excess gasoline should be spilling out of the carb overflow tubes, but can also feed back into the air filter itself--I had this happen with a Yamaha XS650 that I'd left sitting too long.
Figure out what's going on with the carbs--it's probably a simple repair that will take only a few minutes after you succeed in getting the carbs off your motorcycle (a much more time-consuming job, in my experience). Fix that, and your problem should resolve.

I have oil coming through carburator. Is there a vacuum line cloggedor what?


Check your oil level. If your vacuum petcock or float bowls are over flowing gas into the engine, your oil is diluted with gas, the crankcase is too full, gasoline diluted oil is blowing through the breather tube into the air box, and from the air box into the carburetor. Needles sticking in the carburetors can happen at any time even to new motorcycles. If you have vacuum petcocks inspect the vacuum diaphragms for leaking. Clean the carburetors and replace the float needles if they show wear. Change the gas fouled oil and filter. Hope this helps.

My yamaha pw 80 won't kickstart and can you tell me why gas is coming out were the spark plug goes when i try kickstart?


I'm assuming you mean gas comes out the spark plug hole with the plug removed??? You probably have a gummed up carburator, due to old gas or dirt. Make sure your air filter is clean first, and then get your carburator thoroughly cleaned. If your float is sticking, or the float needle is dirty or worn out, it will keep dumping fuel to the engine.

The larger vacuume hose atatchd to the air filter spits oil into the housing


Check to see if you have overfilled the oil supply. My 1980 has the same oil vent pipe terminating in the air box, and if the oil reservoir is over filled it will spit oil into the air box. That line is a breather pipe and it conforms to EPA rules, namely no venting of hydrocarbons to the atmosphere.

I have a 1980 xs650. where are the engine numbers


Generic Comment:

My guess is that a 1980 is points. Look in the area where the cam shaft should be.. Look for a round or oval cover with phillips screws. Pop it off.

Powermate 5000 leaks gas from the air filter..not sure how it's getting into the air filter?


My Coleman Generator 5000w with a Tecumseh 10hp story. Mine engine finally did die before I pulled the carburator off.
On mine the float was defective. It was full of fuel! I repaired the hole in it. I removed the air filter and saw fuel pouring out the side so much that I had a jar to catch it. I removed the carburator and took the nut off the bowl to examine the float. Then I removed the pin holding the hinged end of the float. Carefully pulled it out with the needle valve attached. When I removed the needle valve (just slides on mine) it was free to test. I tested by shaking it near my ear and I could hear the fuel inside the float. Mine was brass or copper. I wiped mine off with a napkin and finally found the hole. I drained the fuel by polking a needle sized hole and removed the fuel. I then soldered the hole shut with using just electronic 60/40 resin solder and a small soldering iron. Mine works like a champ now.
