I've got an older Stihl 038 chainsaw and it appears to be leaking gas. It leaks more when it's in the upright position so I've been storing it on it's side. It's NOT the gas cap. I've checked that, no wetness. I thought it might be the fuel line grommet between the gas tank and the carburetor compartment. And there is no gas pooling up inside the carb compartment. But when I set it down on a surface, I can see gas accumulating and some dripping when I pick it up to use it. It appears to be coming from the bottom side. I used it today, but I won't anymore until I get it fixed. Just trying to avoid an expensive shop visit.
