Steve,

I may be getting senile in my old age but yes I agree the picture looks like
the inside of the drum but which surface is it?  Is it a surface
perpendicular to the shaft or a surface that is parallel with the shaft?  Or
trying another way. Think of the drum as a barrel. Is the surface shown the
inside of the bottom of the barrel or the inside of the side of the barrel?
Unless I am seeing things the picture shows me a surface perpendicular to
the shaft and the inside of the bottom of a barrel. If so that surface isn't
critical.  It is the surface that is parallel to the shaft or the inside of
the barrel side that is important. The surface the brake shoe linings rub
against to provide friction for stopping only when the brake pedal is
depressed. . 

Carburetor/sediment bulb issue.   What isn't clear to me is does the fuel
run out of the carburetor fuel bowl drain when the sediment bowl is fills
up?  Does it flow freely?  If yes everything is copasetic. If it doesn't
then the needle and seat isn't opening up, or there is a plug in the
carburetor gas inlet or a plugged gas line or a plugged sediment bulb
fixture. 

Lets start over. Let's work backwards to the sediment bulb.

 Does the sediment bulb fill up if the gas line is disconnected from the
carburetor and when the sediment bulb fills up does the gas run freely our
of the end of the gas line?   If so then you have a plugged carburetor or a
needle and seat that isn't opening! 

If the answer is No does the sediment bulb fill up if the gas line to the
carburetor is disconnected from the sediment bulb fixture?  If the answer is
yes you have a plugged gas line. If No you have a plugged sediment bulb
fixture.

on the '49 A wheels!

Dean and Cecil,

The pic shows the INSIDE of the drum, where the brake shoes run.  

As for the carb, I have the drain cock open on the carb bowl--that makes no
difference.  Also, I replaced the needle-and-seat, and I have verified that
they are not stuck closed.  The only way the sediment bowl will fill is if
it is loose enough for gas to run out the top of it.  More will run out
there than will drip out of the carb.  The fuel line is clear, the screens
and gaskets are all new, clean, and in the right places.  That's why I am so
confused.

While waiting on the new distributor cap and thinking about this fuel
headache, my boy and I cut grass today.  Then, we decided to work some more
on the '49 A wheels I wrote about last year (I labeled it a '48, but the
numbers apparently have been revised to say it is a '49).  Anyway, we took
the new electric impact out to the shed to see if it would have any effect
on those remaining lug bolts on the wheel I heated, pounded on, and
otherwise cussed so long.  Hey, Presto! it spun them all out in a trice.
Literally three minutes, and all were out.  

Then, I figures, what the hey?  let's try the other wheel.  I had heated it
some but not nearly as much.  We got 2 out of the 7.  Tuesday, if my plans
hold, we'll get the torch out there and apply more heat and get the others.
Since the tractor is so close to the shed wall, I had to drill a hole in the
cedar siding to get the impact on the left side.  Unorthodox, but I was NOT
going to try to move the tractor at that point.  I didn't want to have to
rebuild my cribbing.

Anyway, the weekend has had its challenges and rewards.  I hope the info
above helps folks understand the situation with the fuel and the brakes for
the '51.

Thanks for all the help so far!

The "original" Steve Allen

Steve,

Having a little trouble figuring out if that is the back side of the face of
the drum or not but that particular surface just needs to clean enough to
remove  really major surface issues. The only side that is somewhat
sensitive is the inside surface of the drum that the brake shoe lining rubs
against when activated to stop. .  

After cleaning all loose parts should rotate and slide in their respective
holes with very little finger pressure, No friction. These are the parts I
put anti-seize grease on to try oi keep them from rusting again but not get
grease on the brake shoe surface.   Be somewhat skimpy with the grease but
make sure all surfaces of the moving parts have been covered. 

Does the fuel run out of the carburetor bowl when the sediment bowl fills
up? If not the carburetor float needle and seat is sticking closed.  In a
properly sealed system the sediment  bulb will not fill up because the float
probably is shutting off fuel flow to the carburetor because that carburetor
bowl is probably already full.  Therefore you have an airlock. I usually
loosen the carburetor drain a little and let some fuel run out to fill the
bowl.  If no fuel comes out of the carburetor fuel bowl then you have a
carburetor float that is sticking or a carburetor needle sticking in its
seat.  Once some fuel comes out of the carburetor bowl drain the sediment
bulb should fill up. Now having that in turn drip or leak when the bulb is
full is kind of incongruous since you had an air tight air lock before. Sure
its just not residue from when you were filling up the bulb?

But..... if none of that makes sense and you can get fuel into the
carburetor bowl and you can get the sediment bowl to fill by lessening it
and the tractor will run ignore the problem temporarily. And I will think on
it.   Its been awhile since I've had to deal with a bowl that won't fill.
But I have been there done that.

I have had a rusty screen on top of the bowl, inside the housing that would
prevent gas from going through.?? I just pull the screen out and cut the
line and install an inline filter.? I don't run any gas engine without
inline filters.
