Very cool that you got it running. Started right up! Sounds a lot like the flatty in the Desoto....;)

If they run like that, there's something wrong. The low compression common to flatheads doesn't produce enough torque thrust to cause a shake. I've seen 8-cylinder flattys with a dead hole still idle fairly smooth.

The flat 6 in Fernando doesn't even have an harmonic balancer....:)

Inline sixes do not require a balancer. I've never seen or heard of one that does. They're perfectly balanced internally, and due to their configuration, it would require considerable engineering prowess to design one otherwise.

Oh I'm sure the Germans have done it.
 
Actually I have a OEM harmonic balancer for a mopar flatty 6. Tried to use it on the motor in Fernando...but the fan and pullies wouldn't clear, and line up.
 
I spent some time last night fiddling with the carb. Its a Marvel A.A.6 It idles much lower now and runs cooler.

I had no idea haw to set the thing. I couldn't get it to run at all without shooting gas in it so I took it apart and cleaned the thing out. It's super simple really. It has a brass bowl off to the side and there is a leaver with two positions, one marked "summer" & one marked "winter" the only other adjustments are a idle stop on the throttle linkage and a big ass brass thumb screw above the carb. That one connects to a flap in the throat. It has a brass cup and a spring on the thumb wheel end.

After letting it warm up and with the thumb wheel flap freed up it idles much better. The problem I have now is it appears that there is a small screw and a lock tab missing. The tab would hold the thumb wheel from turning. I can't find any info on this carb anywhere other than what it was used on and kits for it. I can't even find a picture of one to see what the lock tab should look like.

So anyone have a lock tab for a 1928 Marvel A.A.6? :D
 
According to my research, the same, or similar carbs were widely used on tractors well into the 30's, many of which are still in use today. :hmmm:

Do these pics help:

Apparently, for a good number of years, that carb was sold by Sears

as a bolt-on replacement for Model A Ford OEM carbs.


Do you know of anyone into the A's? :hmmm:

No, you have a vibration dampener. Inline sixes, by nature, cannot require balancing nor do they create harmonics. From an engineering standpoint, the inline six configuration is the "perfect engine" wherein the only vibration caused is due to the valvetrain and the inevitable side-loading of the pistons (which is minimized by the drag of an opposing piston "on the backside"). That's why they're so popular with diesel engines and non-American carmakers. Virtually any other configuration is a compromise in some manner.

You can see the carb at 1:30 in the video. I'll post some pictures later today. This one has a brass bowl with a adjustment for "winter" and "summer". The bowl has a brass cover that is held down by a clip. I don't see the clip that should be there for the thumb screw on those pics either. They do show the large brass thumb screw that is the low speed adjustment.

Now I don't know if it is even supposed to be there, There must be something to hold that in one spot. It turns soooooo easy.
 
Well it turns out Mark had a parts carb and it had the parts I needed. Man does this car run nice now. The hesitation is gone and it fires right up. I also got the water pump packing changed out so the water leak is fixed.

I also all but finished the wiring. The headlights are wired up and ready to go other than having one bulb in the kit that is burnt out on the low beam side. Finding a 6volt halogen bulb is not an easy task. I had to order one on line.

Here are a few more pics.

"tiltray" thats pretty cool

so where did you find the 6v halogen/?.....i ask cause i have a bike thats 6v and upgrading to halogen would be a godsend

the "new" wires on such an old girl is almost comical looking
