Ahhhh welcome Michael
a few things to try first
check if there is a spark to the plugs, check that the tank isn't rusted within clean out and free up the carbs
you basically have to follow the system through bit by bit and make sure as far as possible everything is free and is working before starting the ole girl up.... bit like the wife [:D]
Brakes have probably siezed again take these apart bleed through with new fluid etc
