Hi,
It sounds like it is not shifting from second gear to drive. That can be a vacuum leak between the engine and transmission, so the transmission is thinking that you have wide open throttle, no vacuum, and need to say in second gear.
If the engine is running at a really high RPM, that would be your problem.
However if the engine is not making power, and seems very sluggish, and will hardly get out of it's own way, then look for things like a plugged fuel filter, or bad fuel pump, ect.
If the engine sounds normal while warming up and the choke is on, but becomes rough and the exhaust smells of unburned gas while it is running, then the carb floats might be stuck or dirty, or filled with gas so they let in to much gas into the carb. This will cause it to run rich, get 2 MPG and require a carb rebuild. The typical $35 rebuild kit will include new floats, gaskets, ect. But probably no instructions on how to install it.
You might check with a community college and see if they can rebuild your carb as a class project, or look for a good mechanic.
My guess is the engine is running fine, but not shifting into drive.
Good luck,
Fred.
