need to take "float bowl"off clean inspect replace if it leaking....or try to tighten the screw right by it....The screw is a drain soo if it is loose it will drain
Yes! Me and my dad had that same problem. After we shut his blaster off, gas would just start flowing out that drain. It had us stumped for the longest time (mainly because my dad never had time to look at it much) but we tried lots of things.
It ended up being the needle and seat. We replaced the needle and seat and problem solved.
