I was using my Ford 8N to cut the field. It quit. I checked for fire and didn't get any. I checked the coil wire connection through the distributor and found that it was shorted. I fixed that and a ohm meter checked it ok. I then had fire to the plugs. It still wouldnt start. I pulled several plugs and found them somewhat black but no evidence of gas. I took the carburator apart checked the needle and its working ok. The carburator had gas in it. It still wont start. I have ordered a rebuild kit for the carb. I hope that fixes it. Is there any thing else about the carburator that would cause it not to supply gas to the cylinders?
