S&S Super E pouring Gas out of the overflow tube.......
CWP2110
fine short of the carb last week suddenly went so rich i fouled 2 sets of plugs
in 24 hours. I got the carb dialed back in with the exception of a faint pop.
otherwise, the bike ran fine.
so the other night i'm riding, (cold weather) and i pull up to a light. this
guy rolls up and sez "good lookin bike, but you're leaking something bad".
turned out to be gas pouring out of the over flow on the carb..... i shut the
line off and trailered it home.
i pulled the bowl off of the carburator tonight. everything looks fine. the
float is free moving, no residue that i can see. no debris, nothing.... the
bowl gasket is even clolored all the way across except around the overflow
port. all along that edge there's a lighter pattern in the gasket. it dosen't
go to the edge of the gasket but it does go to hole where the over flow port
comes through the gasket.
is it possible that there's enough pressure in that bowl that the gas could
"pour" out of the over flow the way it's doing?
logicly, i'm thinking the gas goes from the pump then to bowl. that would
support the pressure on the gasket theory . but if it goes to the bowl,
<gravity> then the pump, then i don't have clue what the problem is.
the bike is a 99 ultra ground pounder with only 1000 miles on it. ( i just got
it) there's a residue buildup behind the air intake so there's definately been
a lot of blow by. but the carb was set so rich, i can see why.
anyway.... the float looks fine. so what's the problem? why was gas pouring out
of the over flow???

So you messed with the adjustments??

Did you measure the float adjustment?

I assume you are talking about the accelerator pump. Fuel flows from the bowl,
through the accelerator pump, into the venturi of the carb. This is a seperate
circuit and won't cause an overflow.

Blow by? What kind? Gas? Oil? From where?

Hey, there's alot of guess work here okay? But what I think happened is,
you got this 113inch monster and ya had some fun on it, probably turned some
high RPMs and got that bad boy shakin real good, and if it's rigid you shook
the fuck outta it. Consequently you threw your float level out of adjustment
and you started to run real rich.
So you started to mess with the adjustments until you leaned it out enough
to quit fouling plugs. But you never checked the float level.
But now you are overflowing gas. Of course, now the engine isn't using as
much fuel, so the only place it can go is on the ground.
Now what you have to do is start from scratch and re-adjust all the circuits
in your carb.
Start with the float adjustment @1/8" below gasket surface measured on far
side from valve.
Then adjust your idle circuit when motor is hot @ the mid point between too
rich and too lean.
Then you adjust the Accelerator pump by screwing clockwise in until you
contact the arm. ***don't go any farther or you will damage it.*** Then turn
it counter clockwise 3 turns and leave it there. This will give you a base
line for tuning. Screw it in, less pump, screw it out more pump. Get it?
Also, while you have the float bowl off, take a pair of scissors and trim
the center out of the gasket, sometimes the get wet and droop onto the float
and it keeps the valve open.
