Fabulous work! I’d love to be a fly on the wall in your shop as I’ve always been fascinated by pattern making

Allis Chalmers used these carburetors on their early model WC tractors. They had a slightly smaller venturi and did not have the GAV or high speed enrichment circuits that the Ford B used.

Upside down?? Not this boy!! Gravity is your friend with an A! (gotta keep oil in the dipper tray somehow!!) Mr. Pietenpol wrote that the A carb was fine in the air as long as you kept it warm, but it tended to load up and run poorly when bouncing along on the ground (as most A drivers with...

Kind of off topic, but maybe someone here will find it interesting: If the carburetor and intake manifold is separated from the exhaust manifold by much distance for some reason (like a Pietenpol aircraft engine conversion) the A engine becomes a carburetor ice monster. For this reason most Ford...

I thought about posting the mathematical answer that Eystein posted, but took the lazy way out after going through the math. The only thing I would like to add to that post is that the head gasket volume (more than you might think), Valve head volume (enough to make a little difference), and...

A lot depends on how much your pistons hang out above the block, as well as the bore (oversize) of your block, but a combustion chamber volume of about 150cc's should get you close to 6:1.

Vertically. Making the intake wider will reduce flow due to increased leakage around the gears.

I'm working on assembling an engine now, and I just checked mine from the side with a dial indicator as Patrick suggested, although I checked it every 90 degrees at the crankshaft for two turns. Using a new aluminum cam gear from one of the regular suppliers on a new Stipe cam (runs nice and...

Still Looking...

I would be interested in a set of non adjustable B lifters if anyone has some available. Please send me a PM or call me at Five Four Zero-Three Two Five-One Four Zero Six if you can help.

Thanks! The only spec I could find from a Ford source was in the Model T service manual which specified something ridiculously low like 24-28 lbs when compressed to "valve closed" height. Even 34-38 seems low to me though... I guess I've been messing with too much "modern stuff" (early 40's...

Ron: I'm sure that performance and reliability would be affected by less spring tension. I've seen lots of numbers thrown around for seat pressure, but I haven't seen or heard anything about what Ford recommended. The service bulletins aren't much help, can anyone give a definitive spring...

Bump! Still looking... (54o) 325-14o6 in case you like phones better than 'puters. Brett

Looking for a set of Model B Valve Lifters, Ford P/N B-6500. I would prefer NOS or excellent used condition. Let me know what you have. Brett Phillips

Chris: Thanks for posting. What you say makes quite a bit of sense, and I feel that you have revealed something that I was holding out on! Before setting the crank up on V blocks, I tried putting it between centers in the lathe to see if I could indicate it there, but I quickly found that the...
