Sticking Carburetor

Hi,
I find that when my Amphicar is fully warmed up, the carburetor
doesn't come down to full idle without "popping" the throttle pedal a
bit. I've been able to track the problem to the carburetor itself and
not the the linkages. Does anyone know how to fix such a problem
without adding a stronger return spring?
Thanks,

I had a similar intermittent problem when I first got the Amphi that I
attribute to the simple fact that it hadn't run in about 14 years, and
things were just a bit "stiff", especially the various cables. I suppose I
could have replaced the throttle cable, but instead what I did was remove
the end of the throttle cable from the carb linkage so that I could raise it
the cable higher. I then proceeded to drip lots of machine oil down the
metal strand cable, so that the oil worked its way down into the cable
housing and then capillary-wise down inside its guts. Now the action's all
nice and smooth. Barring some mechanical difficulty at the carb, this might
also work for you. One supposes that engine heat might cause the cable to
expand just enough to get a bit stiff and impede the action. A little carb
cleaner spray in the throat and around the linkages probably couldn't hurt
either, though I presume you've already tried this.

Although I don't bother removing the cable anymore, I still dribble or
squirt a bit of oil or WD-40 down into the general direction of the throttle
cable casing now and then as part of a general "clean up" of the engine
compartment every couple of months. Nowadays I'll only use the "AMSOIL
Power Foam Carburetor and Engine Cleaner" (AMSOIL Product Code: "APF") for
this.

Hi Bilgemaster,

If a Newbie to the list (who doesn't even own an Amphi yet) can make a
suggestion:

The very best thing to use for lubricating (and "un-sticking") cables is any
of various brands of "Moly-Lube". This is molybdenum disulfide in an
evaporative carrier. Moly is about 100 times more slippery than teflon, and
when the carrier evaporates you are left with a dry lube on your cables,
impervious to heat, moisture, and other grit and nasties that are liable to
"gum up the works". I have used this stuff, available at any auto parts
place, on motorcycles, lawnmowers, mountain bikes, boats, and cars for
several years.

As the old commercial said it, "Try it.....You'll like it"
