carb problems

[tloch220]

Hi all,
My N600 has run fine the few times I started it, but last time I tried
it wouldn't start and it the carb pumped quite a bit of gas into the air
filter box. Would this be from the float in the carb sticking? I
assume the safe thing to do is rebuilt it, but that seems like a lot of
effort for a carb that was running fine a few days ago. Ideas?
Thanks,
Jon

On honda600 carbs
I completely dismantled my carb and ran it through a ultrasonic cleaner (I clean antique clocks for a living), All the orings on each jet were in poor shape. so, after everything was blown dry, I wrapped a turn or 2 of teflon tape over the orings, And then pushed the jet back into its spot. On the main needle and seat, the seat has a screen on it that's not necessary as long as you have a fuel filter close to the carb (remove the plastic mesh filter and save it) Now on the float needle and seat, I do use a lathe to cut the needle at it's original angle and to remove the worn areas. I also due the same thing to the housing the needle seats in, If necessary, I will use lapping compound to make dead certain that it is a complete shutoff. If you are really careful, you can reuse all the gaskets in the carburetor. ONE YOU HAVE TO BE CAREFUL OF IS THE ACCELERATOR PUMP DIAPHRAGM.
On assembly, as I said wrap any borings with Teflon tape and I used permatex aviation gasketmaker (you paint it on with a brush) on all the flat gaskets (it holds up to gas and oil).
If this sounds like it;s more than you can handle, I can clean and pre-adjust the carb and send it back to you for $50.00
You will need to figure shipping and include enough for return shipping in the same box.
Turnaround will be 2 weeks or less
I also have delrin steering rack bushings. Takes all the slop out of the steering $45.00 for the set
PayPal is fine

If it was running fine a few days ago and now it floods,  I would not rebuild it.  Your needle & seat seems to be the problem.  All your problems are between the fuel inlet and the float.  Try cleaning out the area with some carb cleaner (the stuff in an aersol can).  You can attach a hose to the fuel inlet and blow into it.  As you move the float up and down,  the air flow should be cut off (even if you are blowing hard into the hose).  Check your float that it still floats.  You can float it in gas or water.
BTW, if you are not sure of the age or condition of the float valve, changing out the needle and seat might be a good move from a safety standpoint.  You don't want your valve seat to fail again when the engine is hot since it could lead to a fire.
When you put it back together,  check the float level for the proper setting.  If the float setting is off by 1/10 of an inch,  that is enough to send the fuel economy from 40 mpg down to 20 mpg.

Thanks everyone for the help. I have had chronic problems with "gummy"
gas even after cleaning out the tank and replacing the lines. Sunday I
let the fuel pump empty the last half gallon of gas into a can, then put
fresh gas and fuel system cleaner into the tank. It ran well with no
fuel leaks and started fine when hot. I am wondering if the float
became stuck due to the bad gas. This seems to have happened in the gas
tank, where the formerly operating gas gauge is now stuck at 1/2 tank.
