anyone know where I can find a vid of carb removal/maint. for the B&S 675 series (190cc) mower engine on my Troy-Built 21" mower? it ran great last year & even after replacing oil, fresh gas & air filter, it wont start. it will run ifn I spray starting fluid into the carb, but will run, slowing down to stop within 5 seconds of no spray. i'm no mechanic, but have to try- mower shop said "don't even bring it over for 3 weeks".
