Our Farmall M has had a fuel leak since last year so its been parked until we could get to it. The needle and seat leaked and weeped out the bowl gasket. Also found the sediment bowl shutoff had some pitting in the seat that was allowing fuel to flow past. Pulled the carb 2-weeks ago and got it cleaned up in the sonic cleaner, polished the needle and seat, and replaced the bowl gasket. Had the tractor show last week so I didn't get around to picking up a new sediment bowl until this week. Got it installed and so far no more fuel leaking anywhere.
