car wont start

Sorry, but the 25lb gauge reading your getting throws a wrench in that making it critical to find out why.
My first thought would be a bad gauge, but you need to be sure of what it's actually doing, not just assume it is doing what it is supposed to do.

Do you have any indication of too much fuel?
Like flowing into the intake without the engine running and just the pump on?
before I changed the oil, I would crank it and I would get like a fine mist cloud out of the carb, and gas smell in the garage
