Craftsman LT1000 917.271840 W/21HP Briggs,carb#693479
Origional tuel tank beneath seat leaked so I mounted another small tank on hood. Engine started running rich and flooding. I replaced the float needle and fuel pump diaphragm but flooding continue's. I didn't notice a way to renew seat for needle. My questions. Do'es raising tank above carb increase pressure that fuel pump supply's against needle? Should needle seal well enough to hold added pressure if it is indeed more than it was origionally?
