I tried starting my motor after it was laid up for 6 - 9 months. It started but only in the "reved" up position. It would not idol. I noticed a stream of gas coming from the engine. It stream of gas would also occur when the motor was off and I pumped the fuel ball. I took off the cover(s) and noticed the fuel was coming from just one of the carborators. I'm thinking a stuck float. If this is the problem, are there any gas additives to try before bring the motor in for repair? Anything else I could try before bringing it to a mechanic?<br /><br />Thanks.
