Hey guys I have problem with a BR400. It appears to be leaking gas and is hard to keep running all of a sudden. The reason I say appears is because I have taken it apart and don't see any clear leak, but I fill the tank up and in a couple days the tank is empty but there also is no large pool of gas around it to tell where it is leaking from, just vanished gas and it is sitting inside in my shop where nobody is messing with it or anything like that. If I filled it up, in say 2-3 days with no use it would be empty and you can smell the gas in the shop slightly. I took it out of service of course. It also only seems to run when the tank is completely full after that I can't keep it running so i have switched to my backup. I guess I'll take it to my dealer but anybody else had this happen or have any ideas?
