Ive got a problem with my engine it basically can not idle. Now before this everything was running extremly well. It gets warm and then when it goes to idle it does then stumbles and dies. I dont know what it is. I havent started the engine up in just 2 days. I did see a little oil coming from from intake so it might be a vacuum problem but it did this to when the engine was running fine. So i don't know what to do your help would be greatly appreciated. The carburetor is brand new and the engine to.
