ICS prevents run-on.
It can also be used to improve engine braking and emissions.
81-87 USA FJ60 had deceleration fuel cut off system. It worked at high speed. Emission computer, speed sensor, and vacuum switch are most likely broke.
Cataloge sheet details adjustable vacuum...
Fuel injection system shuts off fuel during de-zilleration to improve engine braking and reduce emissions.
35 year old fuel cutoff system, when new, worked at speed ~40MPH.
Engine braking is handy at 2 MPH.
Original vacuum switch opens at 14 in-HG. NO HELP. Hot idle vacuum is...
If captured nut ain't broke, fix it by slobbering threads with anti-sieze compound.
Nissan KL-60 mounted skid plate to angle bracket on frame. Nut and bolt. Much better.
Coat mating surfaces with oil based roofin tar. Keeps salt water and dissolved oxygen out of tiny

Why was it replaced after less than 1 year ?
I blame 3/4 race intake manifold fitted to 1968 and 69 F-engines.
1970 and later F-eng have skinny intake manifold runners.
Not recently, I fitted a 1972 Asian carb to 1968 F-eng. It had poor low RPM performance.
Cured with 1972 intake...
I replaced my rusted power steering cooler with Copper tube.
Bent 700 feet of 3/8" OD tube (over 600 misteaks) to mimic OEM except; frontmost tube is 1.5" forward,
and push on front cushion clamps are 1.5" longer, and gentle ben. (see foto)
Now it falls out, it only happened once.
1/4" nominal...
Three bolts attach wipermotor to steel panel. Clamped connection can be used to augment original feeble ground circuit.
Sand all lectrical contact points to shinny metal (motor, panel, cowl, frame). Apply 'NO-OX' greeze.
Should imperceptibly speed up wipers.

Old diafram didn't fold nicely. Foto.
When pulled in, new diafram tends to take on wave or ripple shape. No sharp folds.
There might be a market for $ 200 aereospace grade convoluted diaphragm with 100 year warranty.
A large dia gear in Xfer stirs up alota oil. Case pressure pushes oil up 3 inches, and into trany.
Vent is too small and Xfer doesn't have front oil seal.
OEM vent has effective dia of 1/8" at best. Pigtail vent made from 1/2" tube and adaptor should reduce case pressure. ( Depending on...
Air flow goes straight thru DOHC engine, in pulses. DOHC pumps more air than older designs. Most DOHC cam profiles are hotter than flathead and F engines.
Not so with 1FZ-FE cams. Warmer cams are available, they come close to 1966 Alfa specs.
Switching gears, 1951-67 Crusher was...
