It forces itself when shifting to 1st gear then after that it shifts alot easier. I also hear a vaccum line leak by the carb but cant find it.

try going to your local parts store and finding a can of non flamable brake parts cleaner.
spray a little in the area that you hear the leak from( the base of the carb) to pinpoint a vacuum leak you'll notice the engine will change sound once the vacuum leak is detected

odds are you'll find that you base gasket is causing the vacuum leak or a cracked hose
