Hello everyone, I have a Stihl 021 chainsaw. It would not start, it had spark, so I purchased a new carb, hose and filter kit (China) on ebay. 12 bucks, can't beat it. When I place it on it's side to gas it up, gas comes out of the tank vent. What does the part that fits over the vent hole look like? I have these hose pieces in the kit but they have holes in them I assume to vent the tank? Thanks
