HOw Do I Adjust Carb Choke DifficulttTo Warm Up In Cold That CoulD B problem

Try Premium gas. It has a higher flash point and won't ignite as easily, therefore preventing "dieseling"

Pull the breather off and adjust the screw on the linkage where the cables are.

It is your timing. Also put some STP or equivalent engine cleaner in the gas tank to clear some of the gasoline gunk built up. If you are only going on short in town driving, put the additive in the tank and use that as an excuse for a long drive to see some sights and have a lunch out.

Was Told I Had Need Front Seal Makn Surr That I Didnt Need A New Transmission

They may pull you transmission to work on it, replacing the seal, but it should fix your problems. If you want to spend more money you can have them go through the transmission. You should not need a new transmission. If you were leaking fluid it caused the ill-regular shifting due to lack of sufficient tyranny fluid.
