DIY Gascolator

What a striker. I love that engine.

Damn. Sometimes I hate spell checker. I thought I told it to leave that
word alone.

"Striker" was supposed to read "stroker." What a stroker. It can really
chug away in the lower RPM's.

Oh, it also has an impulse Fairbanks-Morse magneto. It will crank on the
first or second pull, every time.

There is a thingummy available from Briggs and Stratton called a "glass bowl
cutoff".
It sits directly under the fuel tank, and has a glass sediment bowl of
approximately the size you describe. *It has one input, one output, and a
shutoff valve on... I think it's the input.

The glass bowl cutoff, the replacement glass bowls, and a picture of both of
them can be seen at:
http://www.briggs.learnsmallenginere...BScarbkits.htm
The assembly is $10.75, the glass bowl replacement is $5.75.

Wouldn't it be easier to drill out one of these for better flow rather
than making one from scratch?

YES! The one in the photo is larger than the one I tested. On the
one I had the bowl came to more of a point and the doohicky holding it
on was made up of four wires and a screw rather than the straps as
shown in the picture.

Dear Tony,

Probably so, but I believe we still need to include such things in the
archive of drawings. Some people don't have access to the retailers
as we have here in the States and there's always the possibility that
WE may not be able to buy such things in the future.

Actually, the tank was located behind the dash on the model A, The
model T tank was under the front seat. That is why you had to back up
a hill since the drop wasn't sufficient to gravity feed the carb. on a
hill.

Dear Ed,

Yes, you are correct. My recollection data-base is seventy years
old. If someone had asked me relative to where we lived (West Avenue
= farm = Model T, vs C Street = house = Model A) I would have aced the
test :-)

Actually I checked it out since my brain is old. I had a 1921 model,
but I found that they moved the tank under the dash in 1926 and 27.

True, I didn't know these things still existed at all.

All right! Finally a topic I have extensive first hand experience with
instead of my usual neophyte airplane builder syndrome, i.e. just
plain ignorant! One of the best sources of a gascolator is found on
the sides of used farm tractors from the 1980’s marketed by Ford but
built in Japan. Mine is a 1310 20 HP diesel engine model but other
models are extensively available in a variety of sizes and HP. Yes,
most other tractor’s have them to. What you have is a small gravity
fed fuel collector bowl in front of the fuel injectors with an equally
small internal filter in place. The fuel bowl is generally plastic but
a simple home made adapter will allow you to put a variety of small
mouthed bottles on it. Even better is these assemblies are available
in either used or new configurations, or as Bob H. would say how good
of a scrounger you are.

Oh, Man. That problem--the disappearance of many components--is
an increasing pain already. I went to the local Radio Shack last week
to buy a couple of 9-volt battery terminal clips and they didn't have
any and the catalog showed them as discontinued. Can you feature that?
And the big electronics shop in the city doesn't have roller-lever
microswitches or a decent selection of potentiometers or even a DPDT
spring-center-off toggle switch. Nor dop they have the employees who
know anything about some of this stuff. It seems that 99.9% of people
are buying everything instead of building it, and either contracting
out the repair of it or tossing it and buying a new one. Sad. And
that's why so many of our young folks have no idea what's under the
hood of a car or the cowl of an airplane, or even inside a simple
switch or lawnmower engine.

Tractor "sediment bowls" are available at TSC for about $55 Canadian.

They have glass bouls thugh, and in Canada you will not get the OK on
a homebuilt / experimental with a glass bowl.

Didn't know that. Got a glass one on my Jodel, but it was
licensed in the '70s. It's a thickwalled (1/4" or 5/16" thick) glass
tube, actually, with cast aluminum or zinc top and bottom pieces. Not
likely to break unless I drop it on the concrete at annual time.
I think, since we have a lathe and mill here, I'll just buy a
chunk of 2" 6061T6 aluminum round bar and machine my own for the
Hummelbird. 2011T3 would be better if I could find it.
