Need Super A "Expert"!

[AL Farmall Boy]

No, haven't had the chance...but I did sell my spare rebuilt Touch Control Block today!!

So now I have some money to pay someone IF I could find someone. But, I am feeling the challenge from you guys, so plan to concentrate on it at least one more time. (I now have a new set of points and condenser.) The sad thing is that this sort of challenge is so much more fun when you have other folks around to work with. It's boring and frustrating by myself!

Oh poor me!!!
OK, no more whining tonight!

Sounds like a weak electrical system/spark to me since you've gone through carburetor. Make sure you have no air leaks anywhere either (gaskets)

Chase,

Yeah...that's probably true.

Question, with the timing mark underneath on the flywheel, how do you guys check the timing? Do you just do a static timing, then adjust/fine-tune it by ear by rotating the distributor? Is there any way to check it with a strobe? Guess I need to get my head back in the 2 service manuals I have!! Would much rather watch and learn from someone else!!

YouTube??

[Dale Finch]

Ooo! That's an idea...I'm always amazed at what you can find on YouTube! I'll check it out.

Yes Dale, it is easiest to set it in the middle and once it is running, just rotate and fine tune by ear. Whenever the tractor is apart, paint that timing mark real good.

[Dale Finch]

I did paint that mark when I first reassembled the tractor , but I was by myself and SURE did get tired of getting up and down!! I just never could figure out how you could lie down there with a timing light!

It will probably be a week or two before I get back to this...my sister from Newaygo, MI, is driving down for a visit.

If you have or can borrow a timing light, connect it to each spark plug wire while it's stuttering. If you show a solid flash, flash, flash, of the timing light on each plug wire, you have a fuel or manifold leak problem. If however some plug wires indicate a stuttering flash that matches the sound, you could have faulty spark plug, plug wire or contact in distributor for that plug. If you show the stuttering or missing flashes on all plug wires, then points, and condenser are common point of failure for all cylinders. Don't forget proper points gap also.

Good Luck

Very good info. Thanks for sharing.

[Dale Finch]

Yes! Great diagnostics path.

Last weekend I couldn't even get it started, so I'll leave the carb (for now), and once my visiting sister heads home, I will grit my teeth and dive back in with these suggestions you all have made. Thx!

I had the same issue with my 48 Super A. I bought and installed a new zenith carb, wires, plugs, cap, rotor and It still would cough and sputter when I advanced the throttle and when under load. I thought maybe I was flooding it. I followed the service manual and adjusted the idle screws and now it runs without any hiccups. I still have to advance the throttle at a reasonable speed but hey it's not the gas pedal in my truck.
