Question about Motorcycles
I would assume the floats are stuck in the carbs as the pump just pumps steady with fuel pouring our thisd hose thast runs down to the bottom of the case on the right side. Am I goin to have to pull carbs and clean them up.Bike parked by seller for 7 years and never started up once never. Its a long story but I am doing the right things to get her running by oiling the cylinder walls and turing it over gently I drained old fuel and flushed it out .I think carbs are gummed up or the floats are stuck hel;p and thanks regards John
Please do the following:
- Remove the spark plugs, pour 4 table spoon full of motor oil into each cylinder and crank it for at least 15 to 20 seconds (with the spark plugs removed).
- Replace the spark plugs.
- Replace the engine oil at short intervals for 3 times.
- Flush the fuel lines.
- Replace the fuel.
- Replace the element air cleaner
- Carefully service the carburetors, free up the clogged air and fuel passages, replace the old gaskets, seals and diaphragms.
- Free up and lubricate all the moving parts with WD 40, wet type contact cleaner, carburetor cleaner and motor oil.

The carbs will have to be completely taken apart and cleaned. Carb cleaner has been known to melt old style pot metal. Note: Count the turns of each adjustment screws and when you to put the back in, you will know where to stop and the engine will be much easier to start. Add an inline fuel filter (cheap clear plastic) as gunk will be coming out of gas tank for a while.

Yes, it sounds EXACTLY like a stuck float. You may be able to fix it yourself depending on how accessable the offending carburetor is. Quite often you can free up a stuck float by setting up a bit of vibration. Give this a try > tap the side of the carb repeatedly using the plasitc end of a screwdriver. You are not looking to hammer the thing to death, just create minor shocks. The shocks / vibration will often free up a stuck float. Please rate this solution and let me know if all went well.

I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.

Testimonial: "I will try it, thanks!"
have you a spark?sounds like ouyr float level is too high and the carbs are flooding,try to decrease the float level,she will not start with too much gas

Thats the float valve seals not shutting off, did you clean them & set the float heights?
The overflows from the carb bottoms must also be blocked for the fuel to fill up the carbs which then leaks into the air filter
Check also that the fuel tap turns off when bike is not running
