Hi Guys - I just got my paper filter kit (along with a header - lots of popping on deccel so I guess its running rich, filter may help lean it out) for my sons Predator 212 which has been a surprisingly strong engine and held up well!

Wanted to use a new B&S engine on an ARCO so that I could keep the gas tank on the engine. Picked up a B&S 525 series because height was good to fit in frame. Screwed up and didn't consider how the carb was mounted on the engine. It has an intake that sets the carb down low right into my rear...
