Hello all,

I get on this forum pretty regularly and read posts but have only ever posted one other time. I appreciate all the help you guys have unknowingly provided in the past. I have done some searching but can?t find a problem quite like mine. If I overlooked it I apologize and will gladly be redirected to the appropriate post.

I?ve got a 1962 Case 310c that has sat for several years. Long story short, I rebuilt the carb and had no luck getting it to start (even with a little starting fluid every now and again). Checked the spark from distributor to plugs and it was fairly bright and easy to see but orange in color. Replaced the coil and checked spark using the coil wire. It will jump about 1/4? to ground and is bright blue. Still weak spark between distributor and plugs. Replaced points, condenser, distributor cap, rotor button, plug wires, and plugs. After all that I still have the same issue (Weak spark between distributor and plugs).

What?s next? I?m not ASE mechanic but I?ve never had this much trouble getting a gas burner running. Any and all advice is greatly appreciated.
 
One quarter of an inch is marginal as far as I am concerned. A good system should jump at least 1/2 inch bright blue, I think you have low voltage at the coil from the switch while cranking,

I would check all the cables and cable ends and condition of the starter, worn bushings will cause drag which saps the cranking voltage, also make sure you have a good strong battery, What is the system voltage while cranking, that will give you a starting point to see what is going on, I would check battery voltage right at the posts while cranking, make some checks and get back to us.
 
New condensers are notorious for being bad out of the box. Might try another one or reinstall the original as a test.
