I have this 1956 John Deere 70 (gas) that would not start last summer. Was busy and after cleaning up the spark plugs and verifying fire on one of the plugs (and attempting to induce ether into the carb - not so easy with the oil bath air cleaner) it would not fire. I just left in alone and used other equipment, but now need to use it this summer. While servicing my other old JD I noticed in the operators manual that there is a fuel screen so took it out and it looked fine. I also primed the carb and charged up the battery. Lo and behold the old beast fired right up (electronic ignition). Good? Yes, but quit running after about 4-5 minutes. Not good. After a while i tried it again and same thing, stopped after 4-5 minutes. My guess here would be possible clog in fuel system (tank to carb) or a coil issue. Don't really think it is a coil problem because outside temp was cool and only ran a few minutes. I had cleaned the sediment bowl before and the fuel in it is clear. If anyone can lend an idea I would be most appreciative. Thanks. Gary
