In regard to Florida's tire and battery fees. The state levies a fee of $1.00 per tire and $1.50 per battery on any new vehicle sold within the state. This also applies when replacing a tire or battery. It is considered an impact fee, rather than a disposal fee. A dealer or parts depot that replaces a tire or battery on a vehicle still has to pay a recycling fee to dispose of the old tire or battery, separate from the "impact fees" collected from the customer.
You stated that if you spray either into the engine it will run on one cylinder. Have you gone thru the carburetor and cleaned the mixture jets yet? Sounds like you have a clogged fuel circuit. If spraying either gets it to run at least one cylinder, you most likely don't have a "spark" problem. I'd look into the carburetor.
