I have tried three different carbs. Still runs the same after trying them. The timing I will check. Maybe the timing jumped somehow? I messed with the idle mixture and idle speed settings on all the carbs. It can be made to idle by retarding the timing and adjusting the mixtures way out, but it runs horribly after that. The demon carb I am currently using has sight glass bowls. So, I can see the float level is fine. I am completely stumped at this point. Thank you for taking the time to reply.
