Hello I have a brigs 14 hp engine bolted to a lawn mower but there is no drive or deck belt so the motor has no load on it. But the problem is when I go to start it it turn the key the starter will spin the engine for a little bit then stop and it will keep repeating the proses it's getting gas the strange part is when I spray some starting fluid in the carb the starter will keep turning it until it starts it may start and stop a few times then keep cranking to start. But one it starts it run pretty good if you shut it off it won't start without starting fluid And sometimes starting fluid won't help. I first thought an electrical problem but starting fluid wouldn't fix an electrical problem also even if you choke it it doesn't matter it still won't start. I would really apresheate any help
