my 3hp B&S engine , about 20yrs old starts up good and runs about 1 hr, then dies. unit is on a 1300 watt gen': just stops at once, no coughing or sputtering any ideas as to problem?
my kohler 13hp won,t start(manual) after sitting for a couple of months, I have to spray carb' cleaner in intake to get it started. once it starts, it'll crank everytime after that, what is causing problem?
