I have been trying on/off for 3 months to get my "brand new" (new to me) 49 B running smoothly. I have tuned it up, adjusted or set about every screw or lever that can be set or adjusted. I have gotten alot of input from you guys in doing this, and I am thankful. But, it still is having the same problem, and that is it sputters, coughs when putting a load on the engine. My AC has a Marvel Schleber carb. I am at the end of my rope now. So, I'm asking once again for some direction. Before you go an tell me to check the timing, I have. It's all set (bought a timing light) now. It was off a little bit, but it still runs the same (poorly). I have adjusted the carb a hundred times. It also now has new spark plug wires (old ones didn't look too old actually). I have replaced all the other ignition parts too (points, rotor, condensor, etc..). Carb has been cleaned twice. Tank has been cleaned/drained. New manifold gasket was put on. Questions: Manifold - Could a bad manifold cause the symptoms I'm having? I don't see any leaks, but did prior to putting a new gasket on. I did repair some pin holes in the manifold when I replaced the gasket. (JB weld). Carb - Some of you have cursed the MS carb. I'm not even sure if my carb belongs on this tractor because I see no model stamping on it. Plus, mine has 2 adjustment screws and a B I saw at the fair last week only had one screw on it's MS carb. Most of you said you have Zenith carbs. At one time Sandy Lake had a rebuilt one avail. I just want to make sure I've done all I can before I plunk down $185 and hope it's the problem. Once again, I am grateful for the help you all have given. But, unless I can figure this out myself and actually use this tractor for the first time (that's right, haven't been able to use it), I may be forced to take it in to have it fixed (perish the thought).
