Carb/jet heaters

Doug, I have read on NTBF where guys have disconnected and remove the wires. They do help with starts in cold weather. Here in Florida, we can get along without them.

The heaters are not for starting. They keep the carbs from icing-up in low temps.
They work on a thermostat like the ones on small airplanes. I think the thermostats are set at 50degrees F.

Thanks. I thought that was the case.

early 36 and 40 horse VW's needed those for really cold areas.
they were an aftermarket rig often installed by dealers.
cleared up a lot of 'mystery' problems.
gotta have some carb heat on
airplanes ya know...

Yes,but the carb heat on small aero engines is actually an alternate air source which feeds air heated by the exhaust into the carb intake to prevent ice formation in the venturi area of the carb. The ones on our carbs seem to be intended to heat the idle jet nozzle. I've disconnected mine without any obvious effect.

VW intake manifolds have an exhaust tube that runs along-side the intake to just under the carb (that wonderful Solex carb) that warms the carburetor. It wasn't much good when driving around town, much like the exhaust heat-exchanger heating system.

ya,
the V dub manifold heat passage gets choked with rust and goop.
a new one works pretty good, the aftermarket carb heater
takes the place of the idle jet adjuster screw.
i splice in a small inline bilge blower
in my vintage VW heater line,
the one under the R seat.
works like a champ!

My 1970 Bus had a gasoline heater. That thing was scary, no one would touch it!
I did have one of those inline fans on my 1969 Bus, it worked fairly well.
I always rodded out the intake heater passage, it would build up with carbon more than anything. It is a job cleaning that thing out!

Believe it or not, DC-3/C-47 had gasoline heaters. I have used them while airborne.

The service manual for my VW showed a barely detailed diagram of the heater and the only instructions were "Servicable by a certified VW mechanic only. Do not attempt to dismantle or service." It was basically a gasoline turbine fan, from what I could make of it.

ya, the inside of those old manifolds would coke up like burnt epoxy.
i finally gave up and just buy new manifolds usually.
the Eberspacher heaters were a hoot, like any machine
they tended to blow up when not maintained.
mainly loose fittings, connectors or plugged up air and feul.
its certainly simpler than an old trumpet with Lucas
sparks and AMALs! and just like them, when you get everything
working right, they're wonderful to have.
heres what the warning sticker was all about:
