I posted on here a few days ago about my mower was running perfect after doing some work to it, I started cutting and it died after a minute or 2. I was able to get it to start again the next day but it did the same thing. I just went out to work on it and noticed I was missing a lot of gas, checked for gas leaks and found none. Checked the oil and it has alot more then its supposed to and of course smells like gas, is there anyway it could be something that's not internal? I have put several hundred dollars into this mower and I would be screwed if it's something major, It's a 25hp briggs engine and a 54"cut troy bilt with 194 hours on it.
