I am not the sharpest with these small engines. I have a Briggs 28B707-1008E1 Engine needs a new carb, due to some moron (not me) leaving out of doors and uncovered. Took the bowl and then the carb off, it was full of that nasty white stuff. So I go to briggs part list and come up with two different carb possibilities. First is a 698171 this replaces numerous other previous models. Next is 498027 (says gravity feed, which this is) replaces all these walbro LMT carb numbers (my carb is a walbro lmt no numbers legible) how do I choose? Thanks Tom
