Home from Deans. Now to try sorting….

First start back home:

And a quick test drive. It’s a little too fast on loose gravel to film and drive:

Thanks Rob. It certainly made my day brighter.

Rich, my pleasure. Still fighting the 5-ball carb at low speed and idle.
Cheers,
Rob

Considering your rough idle makes me wonder what cam do you have in this, or how much lift compared to other cams, like 270, 280, 310, etc.? Just wondering...
Thanks, Keith

Big smile in the second video, good on you Rob, it took some time but are enjoying it again !

Thanks Leo.
Kieth,
Not sure on cam/valve timing? I wish I had paid more attention when it was out. I have one intake lobe drawing:

Did you get the distributor on it?

so if I did my math correct in my brain it has .375 lift , that's a lot of cam compared to a stock T at .250

Tim, we did. Works great! First time I can start the motor cold with the crank.

.375 valve lift, minus valve clearance.
I would call that a radical cam.

Scott,
That may help explain the problems getting it to idle and run smooth at lower rpm. Under load the motor seems to “reach down” and pull through. When I shift in the 2nd video it’s running rough, but pulls through without a miss when I shift to high, even though I don’t change the throttle (because I was holding the camera with my right hand).

One thing about it, it accelerates like a Chebby small block.

On another note, I checked the Model K drawings, and the K motor has the same cam lift as a Model T, .250, if my math is right…

I know you want to use the 5 ball, but if you can try a properly sized schebler, that may answer a couple questions. Have fun!!

Kim, Thanks. Bruce agrees with you. We’ll probably try that at some point. I’m putting a video up on anew link with the motor running on a trailer in near dark to see the explosions. It may be that we are firing a fairly even mixture, but the cam lift and timing may just not be capable of a smooth low engine speed without Ali ding rough.
