 You can disconnect the line going to the carburetor, put a Coke bottle in, have someone crank it and make sure you're getting fuel. If you're getting fuel, then we know that we have a problem inside the carburetor. You hook the line back up, like I said, tap, tap, tap, see if it'll start, pump the gas a lot until it starts because you just got to fill everything back up. And I have a 90 and I switched mine over from carbureted to fuel injected.
