This last fall I bought a bolens 1250 with a plow for snow removal. When I bought it it ran well when it was 70+ outside but would have problems starting below that and would not start at all when it would get down in the 40s. I took it in to a shop to get the carb rebuilt, however the shop mechanic told me that the carb was beyond rebuilding. I ordered a nos carb and installed it and was able to use it to plow snow even when the temp was single digits. Problem is, that I have to choke it to get it to start, and then run it with about half choke. With it running on half choke it emits black smoke and is very touchy about just where the choke is. I've since taken the carb apart, cleaned/inspected bit found nothing, pit it back together and had the same results. I no longer believe that the issue is with the nos carb but instead with the timing. I tried setting the timing today, but without any luck. When I set the points at the widest opening to .23 the timing mark on the flywheel isn't even visible in the timing cutout. when I go to check the gap off the mark, the flywheel has to be retarded about 2" and the pushrod that rides the cam isn't at the highest point yet. Has anyone here had this problem and if so how did you fix it? Forgot to mention, the tractor has the Wisconsin s12d in it
